In functional analysis, a locally convex topological vector space (TVS) is said to be infrabarreled if every bounded absorbing barrel is a neighborhood of the origin.[1]

Properties

  • Every quasi-complete infrabarreled space is barreled.[1]

Examples

  • Every barreled space is infrabarreled.[1]
  • Every product and locally convex direct sum of any family of infrabarreled spaces is infrabarreled.[2]
  • Every separated quotient of an infrabarreled space is infrabarreled.[2]

A closed vector subspace of an infrabarreled space is, however, not necessarily infrabarreled.[2]
