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, implementation and their use in reasoning tasks, ranging from the correctness of software to the properties of formal systems, 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 expressiveness and lucidity of the reasoning process.

LFMTP 2020 will provide researchers a forum to present state-of-the-art techniques and discuss progress in areas such as the following:

Special Session in Honour of Frank Pfenning

To celebrate the 60th birthday of Frank Pfenning and his great many contributions to the topics of LFMTP, one session will be devoted to talks by collaborators and friends of Frank.

Important Dates

All deadlines are established as the end of day (23:59) AoE.


In addition to regular papers, we accept the submission of "work in progress" reports, in a broad sense. Those do not need to report fully polished research results, but should be of interest for the community at large.

Submitted papers should be in PDF, formatted using the EPTCS LaTeX style. The length is restricted to 15 pages for regular papers and 8 pages for "Work in Progress" papers.

Submission is via EasyChair. All submissions will be peer-reviewed and the authors of those accepted will be invited to give an oral presentation of their work at the workshop.


After the workshop we will publish post-proceedings in the Electronic Proceedings in Theoretical Computer Science (EPTCS) series. The authors will be allowed to submit a revised version of their paper to take in account the feedback received during the workshop. Accepted regular papers will be published in the post-proceedings. Authors of selected work-in-progress papers will be invited to submit the full versions of their papers for publication in the post-proceedings, subject to another round of review. Details of the second round review will be announced after the worskhop.
