FSTTCS 2021 is the 41st conference on Foundations of Software Technology and Theoretical Computer Science. It is organised by IARCS, the Indian Association for Research in Computing Science, in association with ACM India. It is a forum for presenting original results in foundational aspects of Computer Science and Software Technology.

Due to the Covid situation in India and the rest of the world, and to rule out uncertainty for authors and the local organizers, FSTTCS 2021 will be held virtually.

Submissions must be in electronic form via EasyChair using the LIPIcs LaTeX style file available here. Submissions must not exceed 12 pages (excluding bibliography), but may include a clearly marked appendix containing technical details. The appendix will be read only at the discretion of the program committee. Simultaneous submissions to journals or other conferences with published proceedings are disallowed.

Accepted papers will be published as proceedings of the conference in the ​Leibniz International Proceedings in Informatics (LIPIcs)​ as a free, open, electronic archive with access to all. Authors will retain full rights over their work. The accepted papers will be published under a ​CC-BY license​. For an accepted paper to be included in the proceedings, one of the authors must commit to presenting the paper at the conference.
