Topology delves into the qualitative properties of geometric shapes and spaces, focusing on aspects preserved under continuous deformations like stretching and bending. It introduces concepts such as topological spaces, continuous functions, and homeomorphisms, and extends to algebraic topology, which uses algebra to solve topological problems. The field has applications in DNA analysis, network design, and data structure optimization, and influences disciplines like computer science and physics.
