Topology is a branch of mathematics that deals with the properties of space that are preserved under continuous transformations, such as stretching, twisting, crumpling, and bending, but not tearing or gluing. It focuses on the concepts of structure, continuity, and convergence, and is often described as "rubber-sheet geometry" because of its emphasis on the flexible and qualitative aspects of geometric forms.
