====================================================================== WST 2021 - Call for Papers 17th International Workshop on Termination http://costa.fdi.ucm.es/wst2021 July 16, 2021, Pittsburgh, PA, United States Co-located with CADE-28 ====================================================================== The Workshop on Termination (WST) traditionally brings together, in an informal setting, researchers interested in all aspects of termination, whether this interest be practical or theoretical, primary or derived. The workshop also provides a ground for cross-fertilization of ideas from the different communities interested in termination (e.g., working on computational mechanisms, programming languages, software engineering, constraint solving, etc.). The friendly atmosphere enables fruitful exchanges leading to joint research and subsequent publications. IMPORTANT DATES: * submission deadline: April 18, 2021 * notification: May 23, 2021 * final version due: June 13, 2021 * workshop: July 16, 2021 TOPICS: The 17th International Workshop on Termination welcomes contributions on all aspects of termination. In particular, papers investigating applications of termination (for example in complexity analysis, program analysis and transformation, theorem proving, program correctness, modeling computational systems, etc.) are very welcome. Topics of interest include (but are not limited to): * abstraction methods in termination analysis * certification of termination and complexity proofs * challenging termination problems * comparison and classification of termination methods * complexity analysis in any domain * implementation of termination methods * non-termination analysis and loop detection * normalization and infinitary normalization * operational termination of logic-based systems * ordinal notation and subrecursive hierarchies * SAT, SMT, and constraint solving for (non-)termination analysis * scalability and modularity of termination methods * termination analysis in any domain (lambda calculus, declarative programming, rewriting, transition systems, etc.) * well-founded relations and well-quasi-orders SUBMISSION GUIDELINES: Submissions are short papers/extended abstracts which should not exceed 5 pages. There will be no formal reviewing. In particular, we welcome short versions of recently published articles and papers submitted elsewhere. The program committee checks relevance and provides additional feedback for each submission. The accepted papers will be made available electronically before the workshop. Papers should be submitted electronically via the submission page: https://easychair.org/conferences/?conf=wst2021 Please, use LaTeX and the LIPIcs style file http://drops.dagstuhl.de/styles/lipics/lipics-authors.tgz to prepare your submission. PROGRAM COMMITTEE: * Martin Avanzini - INRIA Sophia, Antipolis * Carsten Fuhs - Birkbeck, U. of London * Samir Genaim (chair) - U. Complutense de Madrid * Jürgen Giesl - RWTH Aachen * Matthias Heizmann - U. of Freiburg * Cynthia Kop - Radboud U. Nijmegen * Salvador Lucas - U. Politècnica de València * Étienne Payet - U. de La Réunion * Albert Rubio - U. Complutense de Madrid * René Thiemann - U. of Innsbruck * Johannes Waldmann - HTWK Leipzig
