Webcompute the representations and characters of D. 2n. and my thesis will be an explanation of these computations. When n= 2k+ 1 we will show that there are k+ 2 irreducible representations of D. 2n, but when n= 2kwe will see that D. 2n. has k+ 3 irreducible rep-resentations. To achieve this we will rst give some background in group, ring, module, WebLie algebras. For example, the classification of irreducible representations of a semisimple complex or compact Lie group is (at least in the simply-connected case) the same as the clas- ... we see that central extensions are classified by H2(g,a)= Z2(g,a)/B2(g,a). 3.2 Adjoining a derivation A derivation is a local analog of an automorphism ...

WebCorollary 1.4. If V n is the irreducible representation of sl(2;C) with highest weight n, then V n is the direct sum of its weight spaces: V n= V[ n] V[ n+ 2] V[n 2] V[n]; and each weight space is one dimensional. More speci cally, V[n 2k] is generated by v k, where v k= fkv 0 for some highest weight vector v 0. 2. Concrete Expressions for V
Webto λ. As a trivial example, we have the trivial representation R of any group G. Theorem 8 Let W be an irreducible real representation of G. If cW is irreducible as a complex representation, the endomorphism ring End R(W) ∼= R consists of the endomorphisms fw = λw with λ real.
