The category of topological spaces, denoted LaTeX or LaTeX, is the category whose objects are topological spaces and whose morphisms are continuous functions.

Definition

The category LaTeX consists of:

  • LaTeX is the class of all topological spaces;
  • LaTeX is the class of all continuous functions between topological spaces;
  • The composition operation LaTeX is given by the composition of ordinary functions.

Subcategories

Several important subcategories of LaTeX arise by restricting objects:
