FIRST CALL FOR SHORT COMMUNICATIONS AND SOFTWARE PRESENTATIONS ISSAC 2026 International Symposium on Symbolic and Algebraic Computation July 13 - 17, 2026 Carl von Ossietzky Universität of Oldenburg, Germany https://www.issac-conference.org/2026/ ---------------------------------------------------------------------- The International Symposium on Symbolic and Algebraic Computation is the premier conference for research in symbolic computation and computer algebra. ISSAC 2026 will be the 51st meeting in the series, which started in 1966 and has been held annually since 1981. The conference presents a range of invited talks, tutorials, short communications (posters), software demonstrations, and vendor exhibits with a centerpiece of contributed research papers. ISSAC 2026 will be held from July 13 to 17, 2026, at Oldenburg, Germany. The short communications session at ISSAC is a venue to announce early research results or ongoing projects that might not yet be complete. Short communications reporting on recent work published, accepted, or submitted elsewhere are also welcome (with original publications clearly referenced). The short communication submission will be in the form of an extended abstract (see details below). At the conference, short communications will be presented in the form of a poster session. Authors are encouraged to print their poster on a single large A0 sheet. The software presentation sessions at ISSAC are opportunities to demonstrate and communicate about new implementations of algorithms in symbolic and algebraic computation. Of relevance are presentations for new software, new packages, or new developments that present some originality or improved performance compared to the state of the art. Authors are invited to submit an extended abstract in PDF format of no more than 4 pages. The abstracts will be reviewed by the short communications and software committees and relevant experts when needed. The review criteria are content, originality, style, and relevance. The accepted short communication and software abstracts will be published in an upcoming issue of the ACM SIGSAM Communications in Computer Algebra. Important Dates --------------- Short communications (posters): * Abstract submission (.pdf) deadline: May 8, 2026, 23:59 (anywhere on Earth) * Notification of acceptance/rejection: May 25, 2026 * Final version (.tex) due: June 12, 2026 Software presentations: * Submission software presentation deadline: April 24, 2026, 23:59 (anywhere on Earth) * Notification of acceptance/rejection: May 25, 2026 * Final version (.tex) due: June 12, 2026 Submissions ----------- Both for the short communications and the software presentations, the submission is in the form of an extended abstract of no more than 4 pages using the SIGSAM LaTeX style and the CCA templates which are available here: https://www.sigsam.org/cca/ Authors of accepted contributions are expected to present their work at the symposium. Short communications: Please submit via EasyChair at: https://easychair.org/conferences/?conf=issac2026poster Software presentations: Please submit via EasyChair at: https://easychair.org/conferences/?conf=issac2026softwarepre Topics ------ All areas of computer algebra and symbolic mathematical computation are of interest. These include, but are not limited to: Algorithmic aspects: * Exact and symbolic linear, polynomial and differential algebra * Symbolic-numeric, homotopy, perturbation and series methods * Computational algebraic geometry * Polynomial and semialgebraic optimization * Computational group theory and number theory * Quantifier elimination and logic * Computer arithmetic * Summation, recurrence equations, integration, solution of ODEs & PDEs * Symbolic methods in other areas of pure and applied mathematics * AI methods and symbolic computation * Complexity of algebraic algorithms and algebraic complexity Software aspects: * Design of symbolic computation packages and systems * Language design and type systems for symbolic computation * Data representation * Considerations for modern hardware * Algorithm implementation and performance tuning * Mathematical user interfaces * Use with systems such as digital libraries, courseware, simulation and optimization, automated theorem-proving, computer-aided design, and automatic differentiation Application aspects: * Applications that stretch the current limits of computer algebra algorithms or systems, use computer algebra in new areas or new ways, or apply it in situations with broad impact. Satellite Workshops/Conferences: * The organizing committee of ISSAC 2026 invites proposals for Satellite Events aimed at enriching the conference program, attracting a broader audience, and promoting new developments and original research results in all areas of symbolic mathematical computation. Current Satellite Events: * Satisfiability Checking and Symbolic Computation Workshop 2026: https://www.sc-square.org/CSA/workshop11.html * Applications that stretch the current limits of computer algebra algorithms or systems, use computer algebra in new areas or new ways, or apply it in situations with broad impact.
