Fourth Workshop on Logical and Semantic Frameworks, with Applications
28th June, 2009 - Brasília, Brazil


Call for Papers

Scope
Logical and semantic frameworks are formal languages used to represent
logics, languages and systems. These frameworks provide foundations for
formal specification of systems and programming languages, supporting tool
development and reasoning.

The objective of this one-day workshop is to put together theoreticians and
practitioners to promote new techniques and results, from the theoretical
side, and feedback on the implementation and use of such techniques and
results, from the practical side.

Topics of interest to this forum include, but are not limited to:

a.. Logical frameworks
  a.. Proof theory
  b.. Type theory
  c.. Automated deduction
b.. Semantic frameworks
  a.. Specification languages and meta-languages
  b.. Formal semantics of languages and systems
  c.. Computational and logical properties of semantic frameworks
  a.. Implementation of logical and/or semantic frameworks
c.. Applications of logical and/or semantic frameworks
LSFA'09 also aims to be a forum for presenting and discussing work in
progress, and therefore to provide feedback to authors on their preliminary
research. Submissions to the workshop will in the form of full papers. The
proceedings are produced only after the meeting, so that authors can
incorporate this feedback in the published papers.
