The Weyl Character Formula
We have seen that irreducible representations of a compact Lie group G can be constructed starting from a highest weight space and applying negative roots to a highest weight vector. One crucial thing that this construction does not easily tell us is what the character of this irreducible representation will be. The character would tell us not just which weights occur in the representation, but...
متن کاملThe q-Weyl dimension formula
1 The Weyl dimension formula and its q-analogue This material is taken from notes for a joint paper with Zajj Daugherty and Rahbar Virk. Everything here is " well known ". Proposition 1.1. Let g be a finite dimensional complex semisimple Lie algebra etc.etc. ...???? Let ν be a dominant integral weight so that the irreducible module L(ν) of highest weight ν is finite dimensional. Letˆκ 1 = ν, ν ...

G is a connected reductive complex Lie group T ⊂ B is a maximal torus contained in a Borel subgroup of G g, b, t are the Lie algebra of G, B, T . R, Ř are the sets of roots and coroots of T in g, R, Ř are the roots of T in b and their coroots, φα : SL2(C)→ G the homomorphism arising from the sl2-triple (eα, hα, fα) in g (for α ∈ R). X = {λ ∈ t× : 〈λ, Ř〉 ⊂ Z}. X = {λ ∈ X : 〈λ, Ř〉 ⊂ Z≥0}. X̌ = ZŘ ...
متن کاملIntegration formulas for the conditional transform involving the first variation
In this paper, we show that the conditional transform with respect to the Gaussian process involving the first variation can be expressed in terms of the conditional transform without the first variation. We then use this result to obtain various integration formulas involving the conditional $diamond$-product and the first variation.
متن کاملNotes on the Weyl Character Formula
and note that 〈h, e, f〉 = sl2(C). Let u, v be the canonical basis of E = C2. Then each SymE is irreducible with ud spanning the highest-weight space of weight d and, up to isomorphism, SymE is the unique irreducible sl2(C)module with highest weight d. (See Exercises 1.1 and 1.2.) The diagram below shows the actions of h, e and f on the canonical basis of SymE: loops show the action of h, arrows...
