A set of class representatives is a subset of X which contains exactly one element from each equivalence class.

A linear operator A:D(A)->H from its domain D(A) into a Hilbert space H is closed if for any sequence of vectors v_n in D(A) such that v_n->v and Av_n->x as n->infty, it ...

A subset of a topological group which is closed as a subset and also a subgroup.

The clove hitch is the hitch illustrated above that is also called the boatman's knot or peg knot.

Let V be a vector space over a field K, and let A be a nonempty set. For an appropriately defined affine space A, K is called the coefficient field.

If S is an infinite set, then the collection F_S={A subset= S:S-A is finite} is a filter called the cofinite (or Fréchet) filter on S.

In mathematics, the term "collection" is generally used to mean a multiset, i.e., a set in which order is ignored but multiplicity is significant.

Complete digraphs are digraphs in which every pair of nodes is connected by a bidirectional edge.

The graph corresponding to the complete k-ary tree on n nodes is implemented in the Wolfram Language as KaryTree[n, k].

A group L is a component of H if L is a quasisimple group which is a subnormal subgroup of H.
