FRISCO Open Workshop '97

INRIA, Sophia Antipolis, Nice (France), March 18-20, 1997.

The First FRISCO Open Workshop FRISCO'OW 97 was held March 18-20 at Sophia Antipolis (Nice, France. FRISCO is an ESPRIT Long Term Research project dedicated to developing state-of-the-art algorithms for solving systems of polynomial equations, and a framework for delivering implementations of those algorithms in an industrial environment (for more information see The SAC Newsletter, volume 1, pages 11-12 or visit the weg page

FRISCO'OW 97 had two complementary objectives:

Topics of the FRISCO'OW 97 focused on new algorithms for polynomial system solving and on problems or solutions concerning industrial applications involving polynomial equations.

The Program Committee of FRISCO'OW 97 was formed by G. Attardi (Universita di Pisa, Italy), M. Gaetano (Universite de Nice-Sophia Antipolis, France), L. Gonzalez-Vega (Universidad de Cantabria, Spain), Y. Papegay (INRIA Sophia Antipolis, France) and M.-F. Roy (Universite de Rennes, France) with Y. Papegay taking care of the local organization.

The number of participants to the FRISCO'OW 97 was around 50 and the workshop run in a very pleasant atmosphere. The workshop contained three invited external talks to the FRISCO project with each of these talks covering one of the topics entitled as ``Algorithms", ``Systems" and ``Applications". The ``Algorithms Invited talk" was delivered by H. Stetter (Universität Vienna, Austria) who presented his new ideas about computing Groebner Basis for polynomial systems with non exact coefficients under the title Interaction between Algebraic and Numerical Computation. The ``Systems Invited talk" was delivered by J. Davenport (Bath University, United Kingdom) who presented the goals of OPENMATH devoted to define a standard way of representing mathematical objects easily to exchange under the title The OPENMATH Project (see The SAC Newsletter, volume 1, pages 12-17). The ``Applications Invited talk" was delivered by P. Rideau (Aerospatiale, Cannes, France) who presented how to use Groebner Bases together the JAMES software to eliminate the algebraic constraints arising in closed-loop multibody systems under the title Groebner Bases and Dynamics of Multibody systems.

The rest of the communications at the FRISCO'OW 97 can also be classified according the same scheme before described and most of them described the current progress status of the FRISCO project. A look to the titles of the talks in the program can give a clear idea of such status (the book of abstracts of the FRISCO'OW 97 can be obtained upon request to the author of this report).
