                       International Workshop
                                on
                  Classical Logic and Computation

Associated to: ICALP 2008, July 6-13, 2008, Reykjavik, Iceland
Preliminary date: July 13 2008

Scope:

CL&C'08 is the second of a new conference series on "Classical Logic
and Computation". It intends to cover all work aiming to explore
computational aspects of classical logic and mathematics.

The fact that classical mathematical proofs of simply existential
statements can be read as programs was established by Goedel and
Kreisel half a century ago.  But the possibility of extracting useful
computational content from classical proofs was taken seriously only
from the 1990s on when it was discovered that proof interpretations
based on Goedel's and Kreisel's ideas can provide new nontrivial
algorithms and numerical results, and the Curry-Howard correspondence
can be extended to classical logic via programming concepts such as
continuations and control operators.

This workshop aims to support a fruitful exchange of ideas between the
various lines of research on Classical Logic and Computation.
Topics of interest include, but are not limited to,

   - version of lambda calculi adapted to represent classical logic,
   - design of programming languages inspired by classical logic,
   - cut-elimination for classical systems,
   - proof representation and proof search for classical logic,
   - translations of classical to intuitionistic proofs,
   - constructive interpretation of non-constructive principles,
   - witness extraction from classical proofs,
   - constructive semantics for classical logic (e.g. game semantics),
   - case studies (for any of the previous points).


Submission and Publication:

This is intended to be an informal workshop. Participants are
encouraged to present work in progress, overviews of more extensive
work, and programmatic/position papers, as well as completed
projects. We therefore ask for submission both of short abstracts and
of longer papers.  

In order to make a submission:
   - Format your file using the LNCS guidelines; there is a 15 page limit.
   - Use the submission links at http://www.doc.ic.ac.uk/~svb/CLaC08

Submissions will be refereed at normal standards. A participants'
proceedings will be distributed at the workshop. A special issue of a
journal, associated with the workshop, is being considered. It will
contain full versions of selected papers.


Invited speakers:

Helmut Schwichtenberg (Muenchen)
