题  目： Noncommutative convexity and the extremal matrix states on tensor product of C*-algebras

报告人： 吴畏教授     （华东师范大学数学系）

摘  要： In this talk, I will first give a brief survey on the noncommutative convexity theory. Then we discuss the extreme point structure problem of matrix states on tensor product of C*-algebras. We prove that the matrix extreme points of the matrix state space on the tensor product of two unital C*-algebras, at least one of them is of type I, are exactly the isometric orbit of the restrictions, on the exponentially unitary orbit of the C*-algebraic tensor product, of the tensor products of the matrix extreme points of matrix state spaces of the two C*-algebras.
