NettetAll irreducible representations are weakly contained in the left regular representation λ on L2(G). Trivial representation. The trivial representation of Gis weakly contained in the left regular representation. Godement condition. Every bounded positive-definite measure μon Gsatisfies μ(1) ≥ 0. NettetToday we discuss the representations of a cyclic group, and then proceed to define the important notions of irreducibility and complete reducibility (2.1) Concrete realisation of isomorphism classes We observed last time that every m-dimensional representation of a group Gwas isomorphic to a representation on Cm.

NettetSo if we have a matrix representation, then we can think of it as a representation (in our new sense) acting on the vector space Cn. Lemma 1.2.2. Let ˆ: G!GL(V) be a representation of a group G. Let A= fa 1;:::;a ngand B= fb 1;:::;b ngbe two bases for V. Then the two associated matrix representations ˆA: G!GL n(C) ˆB: G!GL n(C) are ...

Denote by λ the left regular representation on L 2 ( G) defined for f ∈ L 2 ( G) and g ∈ G by ( λ ( g) f) ( x) = f ( g − 1 x) for x ∈ G. For f ∈ L 2 ( G) we denote by f ∗ the function defined by f ∗ ( g) = f ( g − 1) ¯ for g ∈ G. classroom of the elite is about
