Abstract

    In this paper, we will study the relation between complex character   and the condition order spectrum   in real and complex ordered Banach algebra  .We prove many properties on it,s . afterwards, we prove that  is upper semi continuous Finally we will show the relation between condition Quasinilpotent  and the radical .
