Macdonald多项式和拟对称Macdonald多项式的紧致公式

Compact formulas for Macdonald polynomials and quasisymmetric Macdonald polynomials

Sylvie Corteel, Jim Haglund, Olya Mandelshtam, Sarah Mason, Lauren Williams

摘要:

我们提出了几个新的和紧凑的公式的修改和积分形式的麦克唐纳多项式,紧凑的“多线队列”公式的麦克唐纳多项式由于Corteel,Mandelshtam和威廉姆斯的基础上。我们还介绍了一个新的准对称模拟Macdonald多项式。这些准对称麦克唐纳多项式细化(对称)麦克唐纳多项式和专门在$q=t=0$的准对称舒尔多项式定义的Haglund,Luoto,梅森,和van Willigenburg。这是一个扩展的抽象。

英文摘要:

We present several new and compact formulas for the modified and integral form of the Macdonald polynomials, building on the compact "multiline queue" formula for Macdonald polynomials due to Corteel, Mandelshtam and Williams. We also introduce a new quasisymmetric analogue of Macdonald polynomials. These quasisymmetric Macdonald polynomials refine the (symmetric) Macdonald polynomials and specialize at $q=t=0$ to the quasisymmetric Schur polynomials defined by Haglund, Luoto, Mason, and van Willigenburg. This is an extended abstract.
