ICTAC 2026 The 23rd International Colloquium on Theoretical Aspects of Computing 11-13 of November, 2026 Bariloche, Argentina https://ictac2026.github.io/ SCOPE The ICTAC conference series aims at bringing together researchers and practitioners from academia, industry, and government to present research and exchange ideas and experiences within theoretical aspects of computing through methods and tools for system development. ICTAC also aims to promote research cooperation between developing and industrial countries. IMPORTANT DATES Abstract deadline: 8-Jun-2026 (AoE) Submission deadline: 15-Jun-2026 (AoE) Notification: 10-Aug-2026 (AoE) Camera ready: 31-Aug-2026 (AoE) INVITED SPEAKERS Erika Ábrahám (RWTH Aachen University, DE) Pablo Barceló (Pontifical Catholic University of Chile - IMFD - CENIA, CL) Nazareno Aguirre (National University of Rio Cuarto, AR) TOPICS The conference concerns all aspects of theoretical computer science, including, but not limited to: - Languages and automata - Semantics of programming languages - Logic in computer science - Lambda calculus, type theory, and category theory - Domain-specific languages - Theories of concurrency and mobility - Theories of distributed computing - Models of objects and components - Coordination models, timed, hybrid, embedded, and cyber-physical systems - Security and privacy - Static analysis - Software verification - Software testing - Program generation and transformation - Model checking and theorem proving - Theory and methods of trustworthy AI - Applications and experiences. SUBMISSIONS We solicit submissions, related to the topics of ICTAC, in the following categories: A. original research contributions; B. short papers, with original work in progress or with proposals of new ideas and emerging challenges; and C. tool papers on tools that support formal techniques for software modeling, system design, and verification. Submissions of regular papers must not exceed 16 pages and short and tool papers should not exceed 8 pages, in both cases excluding bibliography of 2 pages maximum. Submissions must not have been published or be under consideration for publication elsewhere. All submissions will be judged on the basis of originality, contribution to the field, technical and presentation quality, and relevance to the conference’s topics. All contributions to ICTAC 2026 have to be submitted electronically in PDF format via Easy Chair https://easychair.org/conferences/?conf=ictac2026 Papers must be formatted according to the guidelines for Springer LNCS papers (seehttps://www.springer.com/gp/computer-science/lncs), without modifications of margins and other space-saving measures. Authors should therefore consult Springer’s authors’ instructions and use their proceedings templates, either for LaTeX or for Word, for the preparation of their papers. Springer encourages authors to include their ORCIDs in their papers. PUBLICATION All accepted papers in categories A-C will appear in the proceedings of the conference that will be published as a volume in Springer’s Lecture Notes in Computer Science (LNCS) series. All accepted papers must be presented at the conference. Their authors must be prepared to sign a copyright transfer statement. At least one author of each accepted paper must register for the conference by the early registration date, and present the paper.
