Abstract | ||||
In this paper, we investigate the topologically weak concepts of topological groupoids by giving the concepts of a-topological groupoid and a-topological subgroupoid. Furthermore, we show the role of the density condition to allow a-topological subgroupoid inherited properties from a-topological groupoid and the irresoluteness property for the structure maps in a-topological groupoid is studied. We also give some results about the fibers of a-topological groupoids. | ||||
