Abstract: | In this talk, we introduce a new combinatorial model for irreducible characters of simple Lie algebras of classical type BCD, which we call a spinor model. This model turns out to be naturally compatible with type A combinatorics and have several interesting applications in representation theory. As one of its applications, we explain how classical branching rules of irreducible characters in a stable range, including Littlewood restriction rule, can be extended to arbitrary highest weights in a bijective way. |
