1、報告題目: 量子關聯與 Tsirelson 問題

報告人:武俊德教授(浙江大學)

報告摘要: 這個報告里,我將用算子理論和算子代數語言,簡單介紹量子理論的研究進展,包括量子邏輯、量子關聯、貝爾不等式和 Tsirelson 問題等。

報告時間:2020年6月19日下午2:30--3:10

報告地點:釘釘群  會議口令:226 797 16754

2、報告題目: On parallel sum of operators

報告人:鄧春源教授(華南師范大學)

報告摘要: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.
