Topology is a branch of mathematics concerned with the properties of space that are preserved under continuous deformations, such as stretching and bending, but not tearing or gluing. It emerged from geometry and set theory, through the analysis of concepts like continuity, compactness, and connectedness. The key idea in topology is the concept of a topological space, which generalizes the notion of geometric shapes in a more abstract form. Topology can be divided into several subfields such as point-set topology, which deals with the more foundational set-theoretic definitions and properties; algebraic topology, which studies spaces with tools from abstract algebra; and differential topology, which focuses on differentiable functions and their implications. This field has wide applications across various areas of mathematics and science, including the study of dynamical systems, computational biology, and physics, particularly in understanding the properties of space and time and the behavior of the universe at a large scale.
