In mathematics, general topology is the branch of topology that deals with the basic set-theoretic definitions and constructions used in topology. It is the foundation of most other branches of topology, including differential topology, geometric topology, and algebraic topology. Another name for general topology is point-set topology. The fundamental concepts in point-set topology are continuity, …

In topology, a branch of mathematics, a retraction is a continuous mapping from a topological space into a subspace that preserves the position of all points in that subspace. The subspace is then called a retract of the original space. A deformation retraction is a mapping that captures the idea of continuously shrinking a space into a subspace. Spacetime topology - Wikipedia Spacetime topology is the topological structure of spacetime, a topic studied primarily in general relativity.This physical theory models gravitation as the curvature of a four dimensional Lorentzian manifold (a spacetime) and the concepts of topology thus become important in analysing local as well as global aspects of spacetime. The study of spacetime topology is especially important in Induced topology - Wikipedia In topology and related areas of mathematics, an induced topology on a topological space is a topology that makes a given (inducing) function or collection of functions continuous from this topological space.

Lower limit topology - Wikipedia In mathematics, the lower limit topology or right half-open interval topology is a topology defined on the set of real numbers; it is different from the standard topology on (generated by the open intervals) and has a number of interesting properties.It is the topology generated by the basis of all half-open intervals [a,b), where a and b are real numbers. Category:Topology - polycount Topology is the layout of a model, how vertices and edges are placed to create the mesh surface. See the Topology page for tutorials. Topology (disambiguation) - Wikipedia Topology is a branch of mathematics concerned with geometric properties preserved under continuous deformation (stretching without tearing or gluing). Topology may also refer to: Math. Topology, the collection of open sets used to define a topological space
