WebbWe show rigorously that Kohn's theorem does not hold for intrinsic Dirac-Weyl materials with filled Fermi seas where the chemical potential is pinned at the band touching points. 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. The group G has a unitary representation ρ … Visa mer • Pontryagin duality Visa mer Webb13 dec. 2024 · Qualcuno potrebbe spiegarmi i passaggi della dimostrazione della prima parte del teorema di Peter weyl dove si afferma: lo spazio generato dalla combinazione lineare di coefficienti matriciali di rappresentazioni unitarie irriducibili di un gruppo compatto è denso in L2 In English: simple yet high paying jobs

While the name "Peter-Weyl" is reserved for the compact group case, I prefer to talk in greater generality. Let G be a unimodular type I topological group with a fixed Haar measure.

WebbFrom the Peter–Weyl theorem in Wikipedia, this theorem applies for compact group. I wonder whether there is a non-compact version for this theorem.
