topology

n. non-quantitative geometry, branch of mathematics dealing with geometric configurations that remain unchanged by stretching bending or twisting (Mathematics)

Topology (Greek topos, "place," and logos, "study") is a branch of mathematics that is an extension of geometry. Topology begins with a consideration of the nature of space, investigating both its fine structure and its global structure. Topology builds on set theory, considering both sets of points and families of sets.
