The main objective of the research is to link the structure of the proximity space with the topological group structure to establish the central topological group structure. Our basic definition depends on the concept of the central set, which depends on the proximity space, which was used with the central continuous functions in constructing the central topological group. Also, we explained a set of properties related to this structure. We defined the center product of center set which used to establish the central product topological group. Also, we established the central product structure and the central quotient structure to define the central product topological group and the central quotient topological group, and we identified a set of properties associated with these concepts.
