This handbook presents the elements of modern logic, including many current topics, to the reader having only basic mathematical literacy. Computer scientists will find specific examples and important ideas such as axiomatics, recursion theory, decidability, independence, completeness, consistency, model theory, and P/NP completeness. The book contains definitions, examples and discussion of all of the key ideas in basic logic, but also makes a special effort to cut through the mathematical formalism, difficult notation, and esoteric terminology that is typical of modern mathematical logic. The Handbook of Mathematical Logic and Proof Techniques delivers cogent and self-contained introductions to critical advanced topics, including: - Godel's completeness and incompleteness theorems - Methods of proof, cardinal and ordinal numbers, the continuum hypothesis, the axiom of choice, model theory, number systems and their construction - Extensive treatment of complexity theory and programming applications - Presents applications to algorithms in Boolean algebra - Provides a treatment of set theory and applications of logic
