Title:  Really real systems of polynomials

Speaker: Cynthia Vinzant, University of Michigan

Abstract:  Systems of polynomial equations with only real solutions are very special. A natural example is that the derivative of a univariate polynomial with only real zeros again has only real zeros. These systems of polynomial equations often have discriminants that are nonnegative and sometimes sums of squares.  I will talk about the geometry and applications of two fundamental examples: the eigenvalues of a symmetric matrix and the analytic centers of a hyperplane arrangement.

About the speaker:  Cynthia graduated in May 2011, with a PhD in Computational Algebraic Geometry from Berkeley under the direction of Bernd Sturmfels.  Since then she has been a post-doctorate at the University of Michigan in Ann Arbor.  She is very active and has given many talks.  I attended her talks in the SIAM Computational Algebraic Geometry conference in Raleigh, North Caroline in October, 2011  and in AMS meeting in Boston 2012.  Both of them were excellent talks and I highly recommend today's colloquium.

Best,

Tony
