On the Group Inverses of Multiplicative Combinations Associated with Two Idempotents
Duan Yingta · Journal of South China Normal University · 2013
Let H be a complex Hilbert space,the set of all bounded linear operators on H is denoted by B(H). In this note,by using the block-operator matrix technique,the group inverses of multiplicative combinations associated with two idempotents on a Hilbert space is established under some conditions.
