本文研究了Littlewood-Richardson系数的两种不同的单参数推广形式,即Hall多项式和广义逆Kostka多项式,并推导了它们的新的组合公式。我们的组合表达式是密切相关的难题,最初介绍了克努森和陶在他们的工作的等变上同调的格拉斯曼。
We study two different one-parameter generalizations of Littlewood–Richardson coefficients, namely Hall polynomials and generalized inverse Kostka polynomials, and derive new combinatorial formulae for them. Our combinatorial expressions are closely related to puzzles, originally introduced by Knutson and Tao in their work on the equivariant cohomology of the Grassmannian.
