Forms: inverse limits [plural]
Head templates: {{en-noun}} inverse limit (plural inverse limits)
  1. (algebra) A subset of the Cartesian product of all the members of an inverse system, such that a member M of the subset is a sort of “cross section” of the inverse system (as fiber bundle) induced by the morphisms of it. (If i<j in the indexing poset then f_ij:A_j→A_i in the inverse system and if a_i∈A_i, a_j∈A_j are components of M then f_ij(a_j)=a_i). Categories (topical): Algebra
