Mathematical logic is the study of logic within mathematics. Major subareas include model theoryproof theoryset theoryand recursion theory. Research in mathematical logic commonly addresses the mathematical properties of formal systems of logic such as their expressive or deductive power, dissertation multimedia mathematics.
However, it can also include uses of logic to characterize correct mathematical reasoning or to establish foundations of mathematics. Since its inception, mathematical logic has both contributed to, and has been motivated by, the study of foundations of mathematics. This study began in the late 19th century with the development of axiomatic frameworks for geometryarithmeticand analysis. In the early 20th century it was shaped by David Hilbert 's program to prove the consistency of foundational theories.
Results of Kurt GödelGerhard Gentzenand others provided partial resolution to the program, and clarified the issues involved in proving consistency. Work in set theory showed that almost all ordinary mathematics can be formalized in terms of sets, although there are some theorems that cannot be proven in common axiom systems for set theory.
Contemporary work in the foundations of mathematics often focuses on establishing which parts of mathematics can be formalized in particular formal systems as in reverse mathematics rather than trying to find theories in which all of dissertation multimedia mathematics can be developed.
The Handbook of Mathematical Logic [1] in makes a rough division of contemporary mathematical logic into four areas:. Each area has a distinct focus, although many techniques and results are shared among multiple areas. The borderlines amongst these fields, and the lines separating mathematical logic and other fields of mathematics, are not always sharp. Gödel's incompleteness theorem marks not only a milestone in recursion theory and proof theory, but has also led to Löb's theorem in modal logic.
The method of forcing is employed in set theory, model theory, and recursion theory, as well as in the study of intuitionistic mathematics. The mathematical field of category theory uses many formal axiomatic methods, and includes the study of categorical logicbut category theory is not ordinarily considered a subfield of mathematical logic.
Because of its applicability in diverse fields of mathematics, mathematicians including Saunders Mac Lane have proposed category theory as a foundational system for mathematics, independent of set theory, dissertation multimedia mathematics. These foundations use toposeswhich resemble generalized models of set theory that may employ classical or nonclassical logic. Dissertation multimedia mathematics logic emerged in the midth century as a subfield of mathematics, reflecting the confluence of two traditions: formal philosophical logic and mathematics.
Dissertation multimedia mathematics first half of the 20th century saw an explosion of fundamental results, accompanied by vigorous debate over the foundations of mathematics. Theories of logic were developed in many cultures in history, including ChinaIndiaGreece and the Islamic world. Greek methods, particularly Aristotelian logic or term logic as found in the Organonfound wide application and acceptance in Dissertation multimedia mathematics science and mathematics for millennia.
In 18th-century Europe, attempts to treat the operations of formal logic in a symbolic or algebraic way had been made by philosophical mathematicians including Leibniz and Lambertbut their labors remained isolated and little known, dissertation multimedia mathematics.
In the middle of the nineteenth century, George Boole and then Augustus De Morgan presented systematic mathematical treatments of logic. Their work, building on work by algebraists such as George Peacockextended the traditional Aristotelian doctrine of logic into a sufficient framework for the study of foundations of mathematics.
Gottlob Frege presented an dissertation multimedia mathematics development of logic with quantifiers in his Begriffsschriftpublished indissertation multimedia mathematics, a work generally considered as marking a turning point in the history of logic.
Frege's work remained obscure, however, until Dissertation multimedia mathematics Russell began to promote it near the turn of the century. The two-dimensional notation Frege developed was never widely adopted and is unused in contemporary texts. From toErnst Schröder published Vorlesungen über die Algebra der Logik in three volumes.
This work summarized and extended the work of Boole, dissertation multimedia mathematics, De Morgan, and Peirce, and was a comprehensive reference to symbolic logic as it was understood at the end of the 19th century, dissertation multimedia mathematics. Concerns that mathematics had not been built on a proper foundation led to the development of axiomatic systems for fundamental areas of mathematics such as arithmetic, analysis, and geometry.
In logic, the term arithmetic refers to the theory of the natural numbers. Giuseppe Peano [7] published a set of axioms for arithmetic that came to bear his name Peano axiomsusing a variation of the logical system of Boole and Schröder but adding quantifiers. Peano was unaware of Frege's work at the time. Around the same time Richard Dedekind showed that the natural numbers are uniquely characterized by their induction properties.
Dedekind proposed a different characterization, which lacked dissertation multimedia mathematics formal logical character of Peano's axioms.
In the midth century, flaws in Euclid's dissertation multimedia mathematics for geometry became known. Among these is the theorem that a line contains at least two points, or that circles of the same radius whose centers are separated by that radius must intersect.
Hilbert [11] developed a complete set of axioms for geometrybuilding on previous work by Pasch. This would prove to be a major area of research in the first half of the 20th century, dissertation multimedia mathematics.
The 19th century saw great advances in the theory of real analysisincluding theories of convergence of functions and Fourier series. Mathematicians such as Karl Weierstrass began to construct functions that stretched intuition, such as nowhere-differentiable continuous functions.
Previous conceptions of a function as a rule for computation, or a smooth graph, were dissertation multimedia mathematics longer adequate. Weierstrass began to advocate the dissertation multimedia mathematics of analysiswhich sought to axiomatize analysis using properties of the natural numbers, dissertation multimedia mathematics.
The modern ε, δ -definition of limit and continuous functions was already developed by Bolzano indissertation multimedia mathematics, [13] but remained relatively unknown, dissertation multimedia mathematics. Cauchy in defined continuity in terms of infinitesimals see Cours d'Analyse, page InDedekind proposed a definition of the real numbers in terms of Dedekind cuts of rational numbers, a definition still employed in contemporary texts.
Georg Cantor developed the fundamental concepts of infinite set theory. His early results developed dissertation multimedia mathematics theory of cardinality and proved that the reals and the natural numbers have different cardinalities. Inhe published a new proof of the uncountability of the real numbers that introduced the diagonal argumentand used this method to prove Cantor's theorem that no set can have the same cardinality as its powerset.
Cantor believed that every set could be well-orderedbut was unable to produce a proof for this result, leaving it as an open problem in In the early decades of the 20th century, dissertation multimedia mathematics, the main areas of study were set theory and formal logic.
The discovery of paradoxes in informal set theory caused some to wonder whether mathematics itself is inconsistent, and to look for proofs of consistency. InHilbert posed a famous list of 23 problems for the next century, dissertation multimedia mathematics.
The first two of these were to resolve the continuum hypothesis and prove the consistency of elementary arithmetic, respectively; the tenth was to produce a method that could decide whether a multivariate polynomial equation over the integers has a solution.
Subsequent work to resolve these problems shaped the direction of mathematical logic, dissertation multimedia mathematics, as did the effort to resolve Hilbert's Entscheidungsproblemposed in This problem asked for a procedure that would decide, given a formalized mathematical statement, whether the statement is true or false.
Ernst Zermelo gave a proof that every set could be well-ordereda result Georg Cantor had been unable to obtain. The immediate criticism of the method led Zermelo to publish a second exposition of his result, directly addressing criticisms of his proof.
Skepticism about dissertation multimedia mathematics axiom of choice was reinforced by recently discovered paradoxes in naive set theory. Cesare Burali-Forti [19] was the first to state a paradox: the Burali-Forti paradox shows that the collection of all ordinal numbers cannot form a set.
Very soon thereafter, Bertrand Russell discovered Russell's paradox inand Jules Richard discovered Richard's paradox. Dissertation multimedia mathematics provided the first set of axioms for set theory. Zermelo's axioms incorporated the principle of limitation of size to avoid Russell's paradox. Inthe first volume of Principia Mathematica by Russell and Alfred North Whitehead was published. This seminal work developed the theory of functions and cardinality in a completely formal framework of type theorywhich Russell and Whitehead developed in an effort to avoid the paradoxes.
Principia Mathematica is considered one of the most influential works of the 20th century, although the framework of type theory did not prove popular as a foundational theory for mathematics.
Fraenkel [23] proved that the axiom of choice cannot be proved from the axioms of Zermelo's set theory with urelements.
Later work by Paul Cohen [24] showed that the addition of urelements is not needed, and the axiom of choice is unprovable in ZF. Cohen's proof developed the method of forcingwhich is now an important tool for establishing independence results in set theory.
Leopold Löwenheim [26] and Thoralf Skolem [27] obtained the Löwenheim—Skolem theoremwhich says that first-order logic cannot control the cardinalities of infinite structures.
Skolem realized that this theorem would apply to first-order formalizations of set theory, and that it implies any such formalization has a countable model. This counterintuitive fact became known as Skolem's paradox. In his doctoral thesis, Kurt Gödel proved the completeness theoremwhich establishes a correspondence between syntax and semantics in first-order logic.
These results helped establish first-order logic as the dominant logic used by mathematicians. Indissertation multimedia mathematics, Gödel published On Formally Undecidable Propositions of Principia Mathematica and Related Systemsdissertation multimedia mathematics, which proved the incompleteness in a different meaning of the word of all sufficiently strong, effective first-order theories. This result, known as Gödel's incompleteness theoremdissertation multimedia mathematics, establishes severe limitations on axiomatic foundations for mathematics, striking a strong blow to Hilbert's program.
It showed the impossibility of providing a consistency proof of arithmetic within any formal theory of arithmetic. Hilbert, however, did not acknowledge the importance of the incompleteness theorem for some time. Gödel's theorem shows that a consistency proof of any sufficiently strong, effective axiom system cannot be obtained in the system itself, if the system is consistent, nor in any weaker system. This leaves open the possibility of consistency proofs that cannot be formalized within the system they consider.
Gentzen proved the consistency of arithmetic using a finitistic system together with a principle of transfinite induction. Gödel gave a different consistency proof, which reduces the consistency of classical arithmetic to that of intuitionistic arithmetic in higher types. The first textbook on symbolic logic for the layman was written by Lewis Carroll, author of Alice in Wonderland, in Alfred Tarski developed the basics of model theory.
Beginning ina group of prominent mathematicians collaborated under the pseudonym Nicolas Bourbaki to publish Éléments de mathématiquedissertation multimedia mathematics, a series of encyclopedic mathematics texts. These texts, written in an austere and axiomatic style, emphasized rigorous presentation and set-theoretic foundations, dissertation multimedia mathematics. Terminology coined by these texts, such dissertation multimedia mathematics the words bijectioninjectionand surjectionand the set-theoretic foundations the texts employed, were widely adopted throughout mathematics.
The study of computability came to be known as recursion theory or computability theorybecause early formalizations by Gödel and Kleene relied on recursive definitions of functions. In his work on the incompleteness theorems inGödel lacked a rigorous concept of an effective formal system; he immediately realized that the new definitions of computability could be used for this purpose, allowing him to state the incompleteness theorems in generality that could only be implied in the original paper.
Numerous results in recursion theory were obtained in the s by Stephen Cole Kleene and Emil Leon Post. Kleene [32] introduced the concepts of relative computability, dissertation multimedia mathematics, foreshadowed by Turing, [33] and the arithmetical hierarchy.
Kleene later generalized recursion theory to higher-order functionals. Kleene and Georg Kreisel studied formal versions of intuitionistic mathematics, particularly in the context of proof theory.
At its core, mathematical logic deals with mathematical concepts expressed using formal logical systems. These systems, though they differ in many details, share the common property of considering only expressions in a fixed formal language. The systems of propositional logic and first-order logic are the most widely studied today, because of their applicability to foundations of mathematics and because of their desirable proof-theoretic properties. First-order logic is a particular formal system of logic.
Its syntax involves only finite expressions as well-formed formulaswhile its semantics are characterized by the limitation of all quantifiers to a fixed domain of discourse.
