The peter-weyl theorem
Webb7 juni 2024 · The classical Peter-Weyl theorem describes the structure of the space of functions on a semi-simple algebraic group. On the level of characters (in type A) this boils down to the Cauchy identity for the products of Schur polynomials. We formulate and prove the analogue of the Peter-Weyl theorem for the current groups. In particular, in type A … Webb13 apr. 2015 · The Peter-Weyl Theorem shows us how to create complete orthogonal systems of functions for other compact groups. For simplicity, we will focus on compact matrix groups. The discussion here follows that of Deitmar ‘s book, though we will give significantly more detail. Introduction Let be any metrizable locally compact group.

WebbHermann Weyl's original proof from the compact group point of view, based on the Weyl character formula and the Peter–Weyl theorem. The theory of Verma modules contains the highest weight theorem. This is the approach taken in many standard textbooks (e.g., Humphreys and Part II of Hall).

WebbUsing this we can give three different interpretations of the Cauchy identities: (1) Consider both the x - and y -variables as corresponding to representations of the symmetric groups. The Cauchy identities become. ⨁ n ≥ 0 C [ S n] = ⨁ λ σ λ ⊗ σ λ, i.e. the Peter-Weyl theorem for S n. (2) Consider the x -variables as corresponding ...
