In mathematics, the Peter–Weyl theorem is a basic result in the theory of harmonic analysis, applying to topological groups that are compact, but are not necessarily abelian. It was initially proved by Hermann Weyl, with his student Fritz Peter, in the setting of a compact topological group G (Peter & Weyl 1927). The … Visa mer A matrix coefficient of the group G is a complex-valued function $${\displaystyle \varphi }$$ on G given as the composition $${\displaystyle \varphi =L\circ \pi }$$ where π : G → GL(V) is a finite-dimensional ( Visa mer Representation theory of connected compact Lie groups The Peter–Weyl theorem—specifically the assertion that the characters form an orthonormal basis for the space of square-integrable class functions—plays a key role in the Visa mer The second part of the theorem gives the existence of a decomposition of a unitary representation of G into finite-dimensional representations. … Visa mer To state the third and final part of the theorem, there is a natural Hilbert space over G consisting of square-integrable functions, $${\displaystyle L^{2}(G)}$$; this makes sense because the Haar measure exists on G.
