<br/><br/>Thesis (M.Sc.) - Cairo University - Faculty of Science - Department Of Mathematics 
<br/><br/> This thesis consists of four chaptersThe main objective is to investigate , if possible , when a skewgroup ring becomes prime or simpleWe confine ourselves to the case in whichR in torsion and G is a finite nilpotent group ; thus we where able to generalize some of results appeared
