WebDec 7, 2024 · Branching Relations describe how irreducible representations of Sn decompose into irreducible subrepresentations after restriction to S n−1, or after induction to S n+1. We also establish the ... WebSuch expansions of products of Schur functions correspond via the Frobenius map to decomposing various products of irreducible representations of Sn into their irreducible components. In addition, the Schur functions are also the characters of the irreducible polynomial representations of the general linear group over the complex numbers GLn(C).
