Irreducible representations of sn
Webform a complete set of irreducible representations of Sn. Remark 1.1 The simplicity of the definition in 1.5 should be compared with the pages and pages of intricate constructions that characterize the treatments of the representations of the symmetric groups given in recent and past litterature following the work of A. Young. WebEach of these V is an irreducible representation of G over k. Theorem 2. Every representation of G is a direct sum of irreducible representations, each of which is isomorphic to one of those V. Each V occurs in the left regular representation with multiplicity dim K V. In particular, if k is algebraically closed then each K is k.
