International Termination Workshop 2001

                    Preliminary Call for Abstracts

                        INTERNATIONAL WORKSHOP
                              (WST '01)

                       Utrecht, The Netherlands
                           May 20-21, 2001

After the successful international workshops on termination held in

   1. St. Andrews (1993),
   2. La Bresse (1995),
   3. Ede (1997), and
   4. Dagstuhl (1999),

the fifth international workshop on termination will be held in
Utrecht in conjunction with the International Conference on Rewriting
Techniques and Applications (RTA). We hope to attain the same friendly
atmosphere as in past workshops, which enabled fruitful exchanges
leading to joint research and subsequent publications.

This workshop delves into all aspects of termination of processes.
Though, the halting of computer programs, for example, is undecidable,
methods of establishing termination play a fundamental role in many
applications and the challenges are both practical and
theoretical. From a practical point of view, proving termination is a
central problem in software development and formal methods for
termination analysis are essential for program verification. From a
theoretical point of view, termination is central in mathematical
logic and ordinal theory.

Areas of interest to this workshop, include, but are not limited to, the


     Well-quasi-order theory
     Ordinal notations
     Fast/slow growing hierarchies
     Strong normalization of lambda calculi
     Termination of programs
     Termination of rewriting
     Termination of logic programs
     Ordinals and termination orderings
     Hard termination problems/proofs
     Termination methods for theorem provers / verification systems
     Implementations of termination methods
     Applications of termination methods


Extended abstracts of papers (1-3 pages) should be submitted
electronically by February 2, 2001.  Expect notification by March
1. Authors of accepted papers will be expected to attend and present
their paper at the workshop.


The program will eventually be available here.
