Abstract: In this paper, we introduces the property (aBw), a variant of generalized a-Weyl’s theorem for a bounded linear operator T on an infinite-dimensional Banach space X$\mathbb {X}$. We establish several sufficient and necessary conditions for… read more here.

Abstract: We denote the collection of the 2× 2 operator matrices with (1, 2)-entries having closed range by S. In this paper, we study the relations between the operator matrices in the class S and their… read more here.
