幂幺圈群中的仿射几何晶体

Affine geometric crystals in unipotent loop groups

Thomas Lam, Pavlo Pylyavskyy

摘要:

研究了A型仿射几何晶体对应于标准表象对称幂的乘积。这个乘积与R-矩阵作用的商在幂单循环群内部构造。这个商晶体有一个半无限的限制,其中的晶体结构描述的限制比以前出现在研究总的积极性的循环组。

英文摘要:

We study products of the affine geometric crystal of type A corresponding to symmetric powers of the standard representation. The quotient of this product by the R-matrix action is constructed inside the unipotent loop group. This quotient crystal has a semi-infinite limit, where the crystal structure is described in terms of limit ratios previously appearing in the study of total positivity of loop groups.
