Algebraic Topology : On some results of category for source proper groupoid space

Our principle aim is to study on groupoid and topological groupoid especially source proper groupoid space. In this paper, we are concerned with the proper, source proper groupoid. The important point of this work is to obtain some results of source proper groupoid the quantity demand and investment in research and development, while the other model focuses on a more realistic relationship between the quantity, demand and the price.
