New meeting: CL&C'08


CL&C'06 is the first of a new conference series on "Classical Logic and Computation". It intends to cover all work aiming to propose a programming language inspired by classical logic, and a semantics for it.

The fact that classical mathematical proofs of simply existential statements can be read as programs was established by Godel and Kreisel some 50 years ago. But the possibility of programming using a style inspired by Classical Logic (much as functional programming is inspired by Intuitionistic Logic) was taken seriously only after the seminal work of Griffin about typing continuations.

There are today two main lines of research. The first studies some (version of lambda) calculus adapted to represent classical logic, like the symmetric mu-calculs, or the X-calculus. The second studies semantics for programs inspired by classical proofs, like game semantic or learning algorithms. These two directions are often independent. This workshop aims to start a fruitful exchange of ideas in the field.

CL&C'06 is part of ICALP 2006.


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 outlining what will be presented at the workshop and of longer papers describing completed work, either published or unpublished, in the following areas:

  • types for lambda calculus with continuations
  • design of programming languages inspired by classical logic,
  • witness extraction from classical proofs,
  • constructive semantic for classical logic (e.g. game semantic),
  • case studies (for any of the previous points)

In order to make a submission:

Submissions will be refereed at normal standards. A participants' proceedings will be distributed at the workshop. A special issue of APAL associated with the workshop is being considered; this will be discussed at the workshop.
