Recurrent and weakly recurrent points in
It is shown in this paper that if is the Stone-Čech compactification of a group , and satisfying a certain condition, then there is a weakly recurrent point in which is not almost periodic, and if another condition will be added, then there is a recurrent point in which is not almost periodic point.
