De nitions 2.7. Let ’: G!GL(V) be a non-zero representation. ’is irre-ducible or simple if the only G-invariant subspaces of V are f0gand V. ’is completely reducible if V = V 1 V n, where for all i2[n], V iis G-invariant and ...

WebExercise 2.6. 4 Let ’be a representation and P be an invertible matrix. Then ’0(g) = P’(g)P 1 is itself a representation. In fact, every representation of a group can be decomposed into a direct sum of irreducible ones; thus, knowing the irreducible representations of a group is of paramount importance. WebExercise: decompose the following reducible representations Exercise: Prove, from theorems based on the GOT, that all irreducible representations of Abelian groups are one-dimensional. Exercise: In the point group D3h, find the following direct products and identify the irreducible representations that they contain: A1ʼ ⊗ A2ʼ A1ʼ ⊗ A2ʼ reacher explained
