Professor Jianquan Ge, Humboldt Fellow (Beijing Normal University)
Isoparametric polynomials and Hilbert’s 17th problem on sums of squares
We introduce a recent joint work with Professor 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.
Please contact Jiakun Liu if you would like to join the lunch with the speaker after the talk.
