			  Workshop on

            Symbolic-Numeric Algebra for Polynomials

                            SNAP 96

                       15-17th July 1996

                 INRIA Sophia-Antipolis, France


 This meeting is intended as a timely workshop to discuss the emerging
 understanding of problems involving polynomials with inexactly-known
 coefficients.  Such polynomial problems arise, for example, when physical
 measurements or numerical computations are used to specify a polynomial
 system.

 In this context, the usual exact algorithms of computer algebra are not
 applicable and new approaches must be devised:  for example, eigenvalue
 formulations and the singular value decomposition.
 
 Recent exciting progress in this domain, together with visits to Nice of
 some of the workers in this area, make the period of July 15-17 an excellent
 opportunity to review the current state of the art and work towards the
 solution of remaining problems.

 Points of interest include:

     o	GCD computation for polynomials with inexactly-known coefficients.
 
     o  Symbolic-numeric methods for simplifying and solving multivariate
	polynomial systems (eg. Groebner bases).

     o  Matrix methods oriented towards zero-dimensional ideals 
        (eg. multivariate resultants). 

     o  Possible extensions to the higher-dimensional ideal case.

     o  Sound methods for other approximate polynomial problems
        (eg. factorization, Pad\'e approximations).

     o  Software systems enabling efficient implementation of these
        algorithms, taking full advantage of existing numerical libraries
        such as LAPACK and NAG. 

 This meeting is being organized by SAFIR, a common project between
 UNSA, INRIA, and CNRS, and will be held at Sophia-Antipolis, located
 between Cannes and Nice on the French Cote d'Azur.
