[Apologies if you receive multiple copies.] December 18-20, 2023 at IIIT Hyderabad <https://www.iiit.ac.in/>, India Website: https://www.fsttcs.org.in/2023/ FSTTCS 2023 is the 43rd conference on Foundations of Software Technology and Theoretical Computer Science. It is organised by IARCS <http://www.iarcs.org.in/>, the Indian Association for Research in Computing Science, in association with ACM India <https://india.acm.org/>. It is a forum for presenting original results in foundational aspects of Computer Science and Software Technology. This year within Track B, in addition to theoretical results, there is also a focus on soliciting submissions in the areas of Programming Languages and Practical Verification. IMPORTANT DATES (all dates are AoE) Abstract Submission: July 12, 2023 Paper Submission: July 19, 2023 Notification: September 22, 2023 Camera Ready: October 5, 2023 Conference: December 18-20, 2023 Workshops: TBA PAPER SUBMISSION Submissions must be in electronic form via EasyChair <https://easychair.org/my/conference?conf=fsttcs2023> using the LIPIcs LaTeX style file available here <https://submission.dagstuhl.de/documentation/authors>. Submissions must not exceed 15 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) <https://www.dagstuhl.de/en/publications/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 <https://creativecommons.org/licenses/by/3.0/>. For an accepted paper to be included in the proceedings, one of the authors must commit to presenting the paper in person at the conference.
