Normal categories of normed algebra of finite rank bounded operators

Abstract

In this article, we introduce the normal category L(S) [R(S)] of principal left [right] ideals of the normed algebra S of all finite rank bounded operators on a Hilbert space H and is shown that they are isomorphic, using Hilbert space duality. We also described the semigroup of all normal cones in L(S) which is isomorphic to the semigroup of all finite rank operators on H. Further, we construct bounded normal cones in L(S) such that the set of all bounded normal cones in L(S) is a normed algebra isomorphic to the normed algebra S.
