An Application of concepts of topological spaces
In the field of mathematics topology is one of the great tools which can be applied in all aspects of science. It has three concepts: topologies on sets, manifolds, continuous functions and homeomorphism. It has various subfields namely, general topology, differential topology, algebraic topology, geometric topology etc. The concepts of topological space and its subfields can be applied in physics, biology, computer science, robotics, mechanical engineering and even cosmology.
