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 on the one hand and their use in reasoning tasks ranging from the correctness of software to the properties of formal computational systems on the other hand have been the focus of considerable research over the last two decades. This workshop will bring together designers, implementors, and
practitioners to discuss various aspects impinging on the structure and utility of logical frameworks, including the treatment of variable binding, inductive and co-inductive reasoning techniques and the expressivity and lucidity of the reasoning process.


LFMTP 2014 will provide researchers a forum to present state-of-the-art techniques and discuss progress in areas such as the following:

  • Encoding and reasoning about the meta-theory of programming languages and related formally specified systems.
  • Theoretical and practical issues concerning the treatment of variable binding, especially the representation of, and reasoning about, datatypes defined from binding signatures.
  • Logical treatments of inductive and co-inductive definitions and associated reasoning techniques. 
  • New theory contributions: canonical and substructural frameworks, contextual frameworks, proof-theoretic foundations supporting binders, functional programming over logical frameworks, homotopy type theory.
  • Applications of logical frameworks, e.g., in proof-carrying architectures such as proof-carrying authorization.
  • Techniques for programming with binders in functional programming languages such as Haskell, OCaml, or Agda and logic programming languages such as lambda Prolog or Alpha-Prolog. with encoding programming languages theory will be particularly welcome.


In addition to regular papers, we also solicit “work in progress” reports, in a broad sense. Those do not need to report original or fully polished research results, but should be interesting for the community at large.

Submitted papers should be in PDF, formatted using the ACM SIGPLAN style guidelines ( The length is restricted to 8 pages, except for “work in progress” papers, which are restricted to 4 pages. Submission is via EasyChair (

Authors of accepted papers are expected to present their paper at the workshop.


Accepted regular papers will be included in the proceedings, which will be published in the ACM International Conference Proceedings Series, available in the ACM Digital Library. Authors are encouraged to publish auxiliary material with their paper (technical appendixes, source code, scripts, test data, etc.).
