Examples of categories

  • Category of sets [r]: Category whose objects are sets and whose morphisms are functions between those sets. [e]
  • Set [r]: Please do not use this term in your topic list, because there is no single article for it. Please substitute a more precise term. See Set (disambiguation) for a list of available, more precise, topics. Please add a new usage if needed.
  • Category of topological spaces [r]: Category whose objects are topological spaces and whose morphisms are continuous functions. [e]
  • Topological space [r]: A mathematical structure (generalizing some aspects of Euclidean space) defined by a family of open sets. [e]
  • Category of functors [r]: Category whose objects are functors in another category and whose morphisms are natural transformations. [e]
  • Category of schemes [r]: Add brief definition or description
  • Scheme [r]: Topological space together with commutative rings for all its open sets, which arises from 'glueing together' spectra (spaces of prime ideals) of commutative rings. [e]
