%0 Journal Article %T Lattice in Pre A*-Algebra %A Y. Praroopa %A J.V. Rao %J Asian Journal of Algebra %D 2011 %I %X This study is on algebraic structure of Pre A*-algebra. First we recall partial ordering = on Pre A*-algebra and recall that Pre A*-algebra as a Poset. We recall if A is a Pre A*-algebra then (A, =) is a lattice. We define (for any subset L of a Pre A*-algebra) a lattice (L, ?, ?) in a Pre A*-algebra. We define semi lattice, sub lattice and bound elements, bounded lattice, distributive lattice, modular lattice, atoms, dual atoms, irreducible elements in a Pre A*-algebra. We define Pre A*-homomorphism and we prove representation theorem in Pre A*-Algebra also we prove f: A ? P (B) is an isomorphism. %K Pre A-Algebra %K irreducible elements %K dual atoms %K atoms %K lattice %U http://docsdrive.com/pdfs/ansinet/aja/2011/1-11.pdf
