==Invited Talk: On Differences in Proofs Between Intuitionistic and Classical Logic==
Invited talk: On Dierences in Proofs Between Intuitionistic and Classical Logic Aleksy Schubert Institute of Informatics, University of Warsaw ul. S. Banacha 2, 02097 Warsaw, Poland alx@mimuw.edu.pl Abstract The presentation will contrast the complexity results for proving asser- tions in classical and intuitionistic logic. The comparison will be built upon the known results for propositional logic and predicate one. The predicate case will be based upon the Mints hierarchy in intuitionis- tic logic which will be contrasted with its counterpart i.e. the prenex hierarchy in classical logic. The dierences in complexity will be illustrated with examples of par- ticular proving mechanisms that are responsible for the divergence, which should facilitate the understanding of where the mathematics is done constructively.
