Colloquium talk by Chunyuan Deng,
School of Mathematics Science, South China Normal University
Full Description
In this talk, we will report some recent results on the general invertibility of the products and differences of idempotents. The invertibility, the group invertibility and the k-potency of the linear combinations of idempotents will be investigated. In addition, the range relations of projectors and the detailed representations for various general inverses will also be presented.
