Page title:CiteSeerX — Computational Content of Classical Logic
Keywords:CiteSeerX, Thierry Coquand
Description:CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This course is an introduction to the research trying to connect the proof theory of classical logic and computer science. We omit important and standard topics, among them the connection between the computational interpretation of classical logic and the programming operator callcc. Instead, here we put the emphasis on actual mathematical examples. We analyse the following questions: what can be the meaning of a non-effective proof of an existential statement, a statement that claims the existence of a finite object that satisfies a decidable property? Is it clear that a non-effective proof has a meaning at all? Can we always say that this proof contains implicitly, if not explicitly, some effective witness? Is this witness unique? By putting the emphasis on actual mathematical examples, we follow Gentzen who founded natural deduction by analysing concrete mathematical examples, like Euclid's proof of the infinity of prime numbers
