报告摘要：This talk discusses relations among various ranks of Hankel tensors. First, we give an algorithm for computing Vandermonde rank decompositions for all Hankel tensors. Second, for generic Hankel tensors of even order or order three, we prove that the classical cp rank, symmetric rank, border rank, symmetric border rank, and Vandermonde rank all coincide with each other. Third, we discuss some open questions about Hankel tensors.
