algebraic topology

algebraic topology (uncountable)

1. (mathematics) The branch of mathematics that uses tools from abstract algebra to study topological spaces.

   The basic goal of algebraic topology is to find algebraic invariants that classify topological spaces up to homeomorphism, although most usually classify up to homotopy (homeomorphism being a special case of homotopy).

   Although algebraic topology primarily uses algebra to study topological problems, using topology to solve algebraic problems is sometimes also possible.
