Abstract :Let $R$ be an associative ring. An additive map $x\mapsto x^*$ of $R$ into itself is called an involution if insert ignore into journalissuearticles values(i); $insert ignore into journalissuearticles values(xy);^*=y^*x^*$ and insert ignore into journalissuearticles values(ii); $insert ignore into journalissuearticles values(x^*);^*=x$ hold for all $x\in R$. The main purpose of this paper is to study some additive mappings on prime and semiprime rings with involution. Moreover, some examples are given to demonstrate that the restrictions imposed on the hypothesis of the various results are not superfluous.
