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…

Ideal category of a Noetherian ring

P G Romeo, Minnumol P K

In this paper we describe the categories $L_{R}$ , [ $R_{R}$ ] whose objects are left [right] ideals of a Noetherian ring $R$ with unity and morphisms are appropriate $…
