Modules. Schur's lemma. Maschke's theorem. Character theory. Classification of irreducible representations.

Let’s generalize Schur’s lemma: let be a finite direct product of simple -submodules. Schur's lemma applied to reducible representations Let G be a group and Φ ∈ GL m , C an m -dimensional nonsingular but otherwise arbitrary matrix. Moreover, let D red ⊕ ( G ) , which symbolizes the RHS of [27] , be an m -dimensional reducible unitary G matrix representation that is already decomposed into a direct sum of its irreducible constituents. 3.2 Schur’s lemma Schur’s lemma plays a fundamental role in the classiﬁcation of group representations.
