报告摘要：
Given two m by n matrices, one can define the entry-wise product which is known as the Hadamard product or Schur product. With such a product, the matrix space is a commutative Banach algebra. In the talk, I will present some characterisations of linear preservers arising from the Schur products, mainly the Schur homomorphisms and Schur null preserving maps, in both finite-dimensional and infinite-dimensional settings.
