Positive solutions of sparse polynomial systems

HARVARD-MIT-BU-BRANDEIS-NORTHEASTERN

Speaker:

Alicia Dickenstein - Universidad de Buenos Aires

A multidimensional polynomial system is said to be sparse when the monomials present in the polynomials are fixed a priori. I will present classic and recent upper and lower bounds for the number of positive solutions of systems of n sparse real polynomials in n variables. I will also discuss basic open questions.
