Algebra of operators for Q-Schur polynomials
Abstract
We consider algebras acting on Schur and Q-Schur polynomials, corresponding to Kadomtsev–Petviashvili (KP) and BKP hierarchies. We present them in the spirit of affine Yangians, paying special attention to commutative subalgebras, box additivity property of eigenvalues and single hook expansion of operators.
