TYPE-THEORETIC LANGUAGES: PROOF-SEARCH AND SEMANTICS
(in conjunction with CADE-17)
CMU Pittsburgh, Pennsylvania, 16 or 21 June, 2000
Final proceedings will be published as a volume in Electronic Notes in Theoretical Computer Science, Elsevier Science Publishers.
Much recent work has been devoted to type theory and its applications to proof- and program-development in various logical settings. The focus of this workshop is on proof-search, with a specific interest on semantic aspects of, and semantics approaches to, type-theoretic languages and their underlying logics (e.g., classical, intuitionistic, linear, substructural). Such languages can be seen as logical frameworks for representing proofs and in some cases formalize connections between proofs and programs that support program-synthesis.
The theory of proof-search has developed mostly along proof-theoretic lines but using many type-theoretic techniques. The utility of type-theoretic methods suggests that semantic methods of the kind found to be valuable in the semantics of programming languages should be useful in tackling the main outstanding difficulty in the theory of proof-search, i.e., the representation of intermediate stages in the search for a proof. An adequate semantics would represent both the space of searches and the space of proofs and give an account of the recovery of proofs (which are extensional objects) from searches (which are more intensional objects). It would distinguish between different proof-search strategies and permit analyses of their relative merits.
The objective of the workshop is to provide a forum for discussion between, on the one hand, researchers interested in all aspects of proof-search in type theory, logical frameworks and their underlying (e.g., classical, intuitionistic, substructural) logics and, on the other, researchers interested in the semantics of computation.
Topics of interest, in this context, include (but are not restricted to):
Researchers interested in presenting their works are invited to send an extended abstract (up to 10-12 pages)} by e-mail submissions of Postscript files to the Programme Chair (Didier.Galmiche@loria.fr) before April 1, 2000. Papers will be reviewed by peers, typically members of the programme committee. The cover page should include a return mailing address and, if possible, an electronic mail address and a fax number.
