Fourth International Workshop on
Logical Frameworks and Meta-Languages
July 05, 2004

Affiliated with IJCAR'04
Cork, Ireland, July 05, 2004



The workshop program is now online and a preliminary version of the proceedings is available as well.

Logical frameworks and meta-languages form a common substrate for representing, implementing, and reasoning about a wide variety of deductive systems of interest in logic and computer science. Their design and implementation has been the focus of considerable research over the last two decades, using competing and sometimes incompatible basic principles.

We solicit submissions on work in progress and on more mature results. Submissions should be extended abstracts of 5-10 pages sent in PostScript or PDF format to the program chair at


Submission: Mon, Apr 12, 2004
Notification: Mon, May 10, 2004
Final Version: Mon, May 31, 2004

This workshop will bring together designers, implementors, and practitioners to discuss all aspects of logical frameworks. Topics include, but are not limited to:

  • logical framework design
  • meta-theoretic analyses
  • applications and comparative studies
  • implementation techniques
  • efficient proof representation and validation
  • proof-generating decision procedures and theorem provers
  • proof-carrying code
  • substructural frameworks
  • semantic foundations
  • methods for reasoning about logics

Informal proceedings are likely to be published as a volume in the Electronic Notes in Theoretical Computer Science (ENTCS) series and will be available to participants at the workshop. A special issue with invited papers from this workshop in a major journal is under consideration. Please find more information about the way the proceedings will be published on the IJCAR workshop homepage.
