# Differential Geometry Seminar: Jianquan Ge -- Isoparametric Polynomials and Hilbert’s 17th Problem on Sums of Squares

Time: 11AM--12NOON, 1 February 2019

Venue: Access Grid Room (Carslaw 829)

Speaker: Prof. Jianquan Ge (Beijing Normal University)

Title: Isoparametric polynomials and Hilbert’s 17th problem on sums of squares

Abstract: We introduce a recent joint work with Prof. Zizhou Tang on nonnegative
polynomials induced from isoparametric polynomials. We completely solve the
question that whether they are sums of squares of polynomials,  giving infinitely
many explicit examples to Hilbert’s 17th problem.

Lunch: There will be a seminar lunch with the detail announced after the talk.
