霍普夫代数的斜Littlewood-Richardson规则

Skew Littlewood-Richardson rules from Hopf algebras

Thomas Lam, Aaron Lauve, Frank Sottile

摘要:

本文利用霍普夫代数证明了斜Schur函数的Littlewood-Richardson规则的一个版本,它隐含了Assaf和McNamara的一个猜想.我们还建立了Schur P-函数、Q-函数和非交换带状Schur函数的斜Littlewood-Richardson规则,以及k-Schur函数、对偶k-Schur函数和辛群的仿射格拉斯曼的同调的斜Pieri规则.

英文摘要:

We use Hopf algebras to prove a version of the Littlewood-Richardson rule for skew Schur functions, which implies a conjecture of Assaf and McNamara. We also establish skew Littlewood-Richardson rules for Schur P- and Q-functions and noncommutative ribbon Schur functions, as well as skew Pieri rules for k-Schur functions, dual k-Schur functions, and for the homology of the affine Grassmannian of the symplectic group.
