报告人简介:Dragan Rakic,塞尔维亚尼什大学教授,2015年博士毕业于尼什大学,主要研究方向为泛函分析、算子理论、广义逆及偏序理论。在专业杂志上等杂志上发表高质量论文20余篇,并主持塞尔维亚科学基金项目2项、及塞尔维亚与思罗维尼亚双边项目1项。

报告简介 The aim of this short note is to indicate that Rao and Mitra's constrained matrix inverse AcrCR (introduced in 1972) is a direct precursor of recently introduced Drazin's (b,c) outer generalized inverse. Precisely, if one rewrites definition of AcrCR in purely multiplicative language, then it turns out that two inverses coincide. Recently introduced Mary's inverse along an element and Manjunatha Prasad and Mohana's core-EP inverse are the special cases of Rao and Mitra's constrained inverse.
