Countably generated

From Wikipedia, the free encyclopedia

In mathematics, the term countably generated can have several meanings:

  • An algebraic structure (group, module, algebra) having countably many generators, see generating set
  • Countably generated space, a topological space in which the topology is determined by its countable subsets
  • Countably generated module. (Kaplansky's theorem says that a projective module is a direct sum of countably generated modules.)
