متن کاملPlaying cards with Vizing’s demon
We analyze a solitaire game in which a demon rearranges some cards after each move. The graph edge coloring theorems of Kőnig and Vizing follow from the winning strategies developed.
متن کاملDescent Algebras , Hyperplane Arrangements , and Shuffling Cards
Abstract Two notions of riffle shuffling on finite Coxeter groups are given: one using Solomon’s descent algebra and another using random walk on chambers of hyperplane arrangements. These definitions coincide for types A,B,H3, and rank two groups. Both notions satisfy a convolution property and have the same simple eigenvalues. The hyperplane definition is especially natural and satisfies a po...
متن کاملDescent Algebras, Hyperplane Arrangements, and Shuuing Cards
This note establishes a connection between Solomon's descent algebras and the theory of hyperplane arrangements. It is shown that card-shu ing measures on Coxeter groups, originally de ned in terms of descent algebras, have an elegant combinatorial description in terms of randomwalk on the chambers of hyperplane arrangements. As a corollary, a positivity conjecture of Fulman is proved. 2
