Categories of bundles and categories of chains
P G Romeo, Riya Jose
K. S. S. Nambooripad introduced an interesting class of categories known as normal categories, which are categories with subobjects, morphisms admitting factorization and having su…
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 and also locate the idempotents for the semigroups and . Fur…
Chain Bundles and Category of Chains
P. G. Romeo, Riya Jose
In [7], we introduced the category of chain bundles with examples and established its significance. Here we shall describe certain categories which we call the category of chains i…
Category of chain bundles
P G Romeo, Riya Jose
For a category with subobjects and factorization, here we describe a new category which we call category of chain bundles and it is shown that this new category is also a category…
