Description: Title: Waring and tensor ranks

Abstract: The problem of expressing a homogeneous polynomial as a sum of powers of linear forms is very classical and goes back to the work of Sylvester, Hilbert, Scorza and many others. The rank of a homogeneous polynomial is the smallest number of linear forms such that the polynomial admits such a representation. The tensor rank is the analogous notion for tensors. In this talk, we will introduce these notions through examples and describe directions of current research.
