Baer Group Rings with Involution

We prove that if a group ring $RG$ is a (quasi) Baer $*$-ring, then so is $R$, whereas converse is not true.      Sufficient conditions are given so that for some finite cyclic groups $G$,     if $R$ is (quasi-) Baer $*$-ring, then so is the group ring $RG$.     We prove that if the group ring $RG$ is a Baer $*$-ring, then so is $RH$ for every subgroup $H$ of $G$.     Also, we generalize results of Zhong Yi, Yiqiang Zhou (for (quasi-) Baer rings) and  L. Zan, J. Chen      (for principally quasi-Baer and principally projective rings).
