                      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 will be virtual ***
======================================================================

[The submission deadline was extended to May 9, 2021].

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:  May 9, 2021 (extended)
  * notification:         June 6, 2021
  * final version due:    June 20, 2021
  * workshop:             July 16, 2021


INVITED SPEAKERS:

  TBA


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:
