WebDefinition 3.0.0: Let G be a group, and S a subset of G. We say that S generates G (and that S is a set of generators for G) if every element of G can be expressed as a product of elements of S and their inverses. We include the inverses of the generators in the definition because we know that every element has an inverse. WebProof. Suppose k 2Z and let K = fn 2Z : njkgand S = fn 2Z : njk2g. Let x 2K so that xjk. We can write k = ax for some a 2Z. Then k2 = (ax)2 = x(a2x) so xjk2. Thus, x 2S. Since any element x in K is also in S, we know that every element x in K is also in S, thus K S.

WebSep 3, 2024 · A subset G of C (X), the set of all continuous real-valued functions on a space X is a generator provided: whenever a point x is not in a closed set C then for some g in G we have g (x) not in the closure of g (C). Equivalently G is a generator if {g^ (-1) U : U open in R and g in G} is a base for X. WebThis site based on the Open Logic Project proof checker.. Modifications by students and faculty at Cal.
