We recall that, in linear algebra, a flag refers to such an increasing sequence of subspaces of a vector space, and hence we name these solutions flag integrable models. By using the boost operator method, we find three non-trivial infinite families of in- tegrable spin chains that have ...

摘要: Using Ram's theory of alcove walks we give a proof of the Bernstein presentation of the affine Hecke algebra. The method works also in the case of unequal parameters. We also discuss how these results help in studying sheaves of nearby cycles on affine flag manifolds. 关键词: quadrati...
