Title: Polynomials on Tensor Spaces

Abstract: Linear mappings are represented by matrices, and their symmetry by left and right multiplication by invertible matrices severely restricts the polynomials that can vanish on them and still respect this symmetry. Likewise for multilinear mappings (tensors), polynomials on hyper-matrices, have beautiful symmetry, which can be used to reduce very large computations. I’ll explain recent results that use this idea to disprove (refine) a conjecture of Holtz and Sturmfels.
