2、报告题目: On parallel sum of operators

报告人:邓春源教授(华南师范大学)

报告摘要:The basic properties of the parallel sum were developed for nonnegative matrices in  finite-dimensional spaces. However, without suitable restrictions, very little of the preceding theories will hold for bounded linear operators  $A$ and $B$ acting in Hilbert space. In this paper, generalization to non-selfadjoint operators is considered  and various properties of parallel sum $A:B=A(A+B)^\dag B$ are given. Meanwhile, the common upper and lower bounds of  positive operators by using the parallel sum are given and some  relationships between the parallel sum of projection operators are obtained.
