In this paper, we use some specific properties that are enjoyed by group elements with non-zero Hattori-Stallings rank function and define, by homological means, a large class of groups that satisfy Bass’ conjecture. We examine closure properties of that class and exhibit certain examples of groups which are contained therein.
