Dear All This is a reminder for the Call for Papers for FSTTCS ( https://www.fsttcs.org.in/2026/ ). FSTTCS 2026 is the 46th conference on Foundations of Software Technology and Theoretical Computer Science. It is organized 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. Within Track B, there is a focus on soliciting submissions in the areas of Programming Languages and Practical Verification, in addition to theoretical results. FSTTCS 2026 will be held at *IIT Delhi, New Delhi* , India during December 16 –18, 2026. The conference is being organized as an in-person event. **List of Topics** **Track A** ● Algebraic Complexity ● Algorithms and Data Structures ● Algorithmic Graph Theory and Combinatorics ● Approximation Algorithms ● Combinatorial Optimization ● Communication Complexity ● Computational Geometry ● Computational Learning Theory ● Cryptography and Security ● Data Streaming and Sublinear algorithms ● Economics and Computation ● Foundations of Machine Learning ● Parallel, Distributed and Online Algorithms ● Parameterized Complexity ● Proof Complexity ● Quantum Computing ● Randomness in Computing ● Theoretical Aspects of Computational Biology ● Theoretical Aspects of Mobile and High-Performance Computing **Track B** ● Automata, Games and Formal Languages ● Logic in Computer Science ● Modal and Temporal Logics ● Models of Concurrent, Distributed and Mobile Systems ● Models of Timed, Reactive, Hybrid and Stochastic and Quantum Systems ● Finite Model Theory and Database Theory ● Formal Methods ● Principles and Semantics of Programming Languages ● Program Analysis and Transformation ● Specification, Verification and Synthesis ● Analysis and Verification of AI ● Theorem Proving and Decision Procedures ● SAT and SMT solving ● Formal Analysis of Security and Privacy **Submission Guidelines** Submissions must be in electronic form via EasyChair using the LIPIcs LaTeX style file available here (link to be added). 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. Reviewing for FSTTCS 2026 is *double-blind*. Hence, authors must make a reasonable effort to ensure that their identity is not easily revealed from the submission itself. Specifically, kindly replace your name and affiliation on the first page with the submission number and do not include any acknowledgements in your submission. Also, authors should cite their prior work in a neutral manner (i.e., instead of saying “ We showed”, please write “ XYZ et al. showed”). Submitting a paper that is available at a public preprint server (such as, arXiv) is admissible. In that case, please do not cite that version of your work in the submission itself. Submissions violating the page limit or the double-blind policy may face desk rejection. 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. *Important Dates* Abstract submission deadline July 4 ( Sat ) 2026 Submission deadline July 11 ( Sat ) 2026 Paper assignment July 15 ( Wed ) 2026 Reviews due Aug 22 ( Sat ) 2026 Rebuttal Aug 26 -28 ( Wed - Fri ) 2026 Discussion Aug 29 ( Sat ) 2026 onwards Notification Sep 15 ( Tue ) 2026 Conference and workshops Dec 15 -20 2026 -- *Confidentiality Notice:* This email and any attachments may contain confidential or privileged information.
