Nirmala Kumari %J Asian Journal of Mathematics & Statistics %D 2012 %I Asian Network for Scientific Information %X This manuscript illustrates the essential congruence ¦Èx on a Pre A*-algebra A and arrive at a variety of properties of these. Also it bear out certain properties of the operations ¦£x(p, q) and ¦µx. It has been confirmed that ¦È is a factor congruence on A if and only if ¦È = ¦Èx for some x¦ÅB(A). Further it was proved that the centre B (A) of a Pre A*-algebra A with 1 is isomorphic with the Boolean centre B(A) of A. %K boolean centre %K balanced congruence %K factor congruence %K boolean algebra %K congruence %K centre %K Pre A*-algebra %U http://docsdrive.com/pdfs/ansinet/ajms/2012/150-157.pdf
