n A restriction; a bound beyond which one may not go.
n (mathematics) A value to which a sequenceconverges. Equivalently, the common value of the upper limit and the lower limit of a sequence: if the upper and lower limits are different, then the sequence has no limit (i.e., does not converge).
n (mathematics) Any of several abstractions of this concept of limit.
n (category theory) Given diagramF : J → C, a cone (L, φ) from L ∈ Ob(C) to F is the limit of F if it has the universal property that for any other cone (N, ψ) from N ∈ Ob(C) to F there is a unique morphismu : N → L such that for all X ∈ Ob(J), .
