数学系Seminar1956期 Preservers on Schur products

报告主题:Preservers on Schur products
报告人:林英芬博士(英国女皇大学)
报告时间:2019年12月13日(周五)15:00-16:00
报告地点:校本部G507
邀请人:朱佩成
主办部门:理学院数学系
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.
