WebAug 12, 2024 · The number of irreducible representations (rows) must equal the number of classes (columns). This results in all character tables being square. e.g. In C2v, there are … 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. Otherwise, we have the decomposition cW = V 1 ⊕V
