Sanvesh Srivastava,Rebecca W. DoergeThroughout this book we assume familiarity with the standard notations and basic results of informal set theory, as found in . We use the following notation for sets of numbers.

Columbia University Statistics,We begin our study of computability by describing one of the earliest mathematical models of computation, one for which the underlying informal picture is especially easy to understand—the Turing machine.

Bending of Curved Bars and Rigid Frames,We begin this chapter by studying in some detail a proof of the fundamental result of computability theory: the undecidability of the halting problem. This will lead us into a discussion of computable real numbers, .-ary expansions, and the elements of computable analysis. You are encouraged to limber up by trying the following exercises.
