论文摘要

在[Dugan-Glennon-Gunnells-Steingrimsson-2019]中,作者介绍了分层树来定义某些颤动的对象,以对某些同质品种上的某些颤音和圆环轨道进行绝对不可分配的表示。在本文中,我们使用theta运算符,该操作员在[d'd'dderio-iraci-vandenwyngaerd-theta-2021]中提出,提供了一个对称函数公式,以列举这些树。然后,我们制定了一个扩展此结果的一般猜想,其中一种特殊情况可能会提供一些有关如何制定统一的Delta猜想的见解[Haglund-Remmel-Wilson-2018]。

In [Dugan-Glennon-Gunnells-Steingrimsson-2019], the authors introduce tiered trees to define combinatorial objects counting absolutely indecomposable representations of certain quivers, and torus orbits on certain homogeneous varieties. In this paper, we use Theta operators, introduced in [D'Adderio-Iraci-VandenWyngaerd-Theta-2021], to give a symmetric function formula that enumerates these trees. We then formulate a general conjecture that extends this result, a special case of which might give some insight about how to formulate a unified Delta conjecture [Haglund-Remmel-Wilson-2018].
