Computability and Logic has become a classic because of its accessibility to students without a mathematical background and because it covers not simply the staple topics of an intermediate logic course, such as Godel"s incompleteness theorems, but also a large number of optional topics, from Turing"s theory of computability to Ramsey"s theorem. Including a selection of exercises, adjusted for this edition, at the end of each chapter, it offers a new and simpler treatment of the representability of recursive functions, a traditional stumbling block for students on the way to the Godel incompleteness theorems. Это и многое другое вы найдете в книге Computability and Logic (George S. Boolos, John P. Burgess, Richard C. Jeffrey)
