Nirmala Kumari %J Asian Journal of Mathematics & Statistics %D 2013 %I Asian Network for Scientific Information %X This study characterizes the distinct partial orders ¡Ü* and ¡Ü? taking place on a Pre A*-algebra A. As a consequence achieve a result that x¡Ü*y if and only if y~¡Ü?x~ . The Hasse diagrams are sketched for certain Pre A*-algebras with respect to =* as well as ¡Ü?. Further derived equivalent conditions for a Pre A*-algebra A to be a Boolean algebra or a trivial Pre A*-algebra in terms of the partial orders ¡Ü* and ¡Ü?. %K Boolean algebra %K center %K semilattice %K poset %K Pre A*-algebra %U http://docsdrive.com/pdfs/ansinet/ajms/2013/23-32.pdf
