Normal categories of normed algebra of finite rank bounded operators

P G Romeo, A Anju

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…

Ideal lattices of semigroup of doubly stochastic matrices

P G Romeo, Riya Jose

In this paper we illustrate the rule for finding number of idempotents in the doubly stochastic matrix $D_{n}$ and also locate the idempotents for the semigroups $D_{3}$ and $D_{4}$ . Fur…
