具有多余网格的网格阵列

Mesh patterns with superfluous mesh

Bridget Eileen Tenner

摘要:

网格模式是经典排列模式的推广,包括经典的,bivincular的,Bruhat限制模式,和一些禁止模式。在本文中,我们描述了所有的网格模式,其避免是符合经典的避免,在某种意义上宣布,额外的数据的网格是不必要的,这些模式。我们还描述了具有最少的多余网格的排列,以及具有最多的排列,在每种情况下列举多余的网格。

英文摘要:

Mesh patterns are a generalization of classical permutation patterns that encompass classical, bivincular, Bruhat-restricted patterns, and some barred patterns. In this paper, we describe all mesh patterns whose avoidance is coincident with classical avoidance, in a sense declaring that the additional data of a mesh was unnecessary for these patterns. We also describe the permutations having the fewest superfluous meshes, and the permutations having the most, enumerating the superfluous meshes in each case.
