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


The workshop will be co-located with CADE-28, which will be in Pittsburgh, Pennsylvania, United States.

Due to the COVID-19 pandemic, CADE and LFMTP will be held online.

Important Dates


In addition to regular papers, we welcome/encourage 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 style guidelines. The length is restricted to 15 pages for regular papers and 8 pages for "work in progress" papers.

Submission is via EasyChair.


A selection of the presented papers appears in the Volume 337 of the Electronic Proceedings in Theoretical Computer Science (EPTCS).

A pdf of the entire proceedings suitable for printing is available here. To ensure perfect centering on A4 paper when printing from acroread, use: "Page Scaling: None" and "Auto Rotate and Center".
