%0 Journal Article %T Characterization of Distributive and Standard Ideals in Semilattices %A ES Rama Ravi Kumar %A J Venkateswara Rao %A V Srinivas kumar %J Momona Ethiopian Journal of Science %D 2011 %I Mekelle University %X This paper investigates the concepts of distributive ideal, dually distributive ideal and standard ideal in a join semilattice. It concerns with the property of ideals in a distributive semilattice. We obtain a characterization theorem for distributive (dually distributive) and standard ideal in a join semilattice. We establish the necessary and sufficient condition for a distributive ideal to be standard ideal. Finally, we bear out the fundamental theorem of homomorphism and Isomorphism theorem of standard ideal. %U http://www.ajol.info/index.php/mejs/article/view/63682
