超八面体下降算子的本征值及其在洗牌中的应用

The Eigenvalues of Hyperoctahedral Descent Operators and Applications to Card-Shuffling

C. Y. Amy Pang

摘要:

本文将Mantaci和Littenauer的作用于自由结合代数的代数推广到作用于所有分次连通霍普夫代数的算子向量空间。这些算子是某些对合的卷积产物,我们认为这是帕特雷下降算子的超八面体变体。我们获得了所有新运算符的本征值和重数,以及类似于亚当斯运算的子类的本征向量的基础。我们概述了如何应用这个特征数据来研究马尔可夫链,并详细研究了洗牌与翻转或旋转的情况。

英文摘要:

We extend an algebra of Mantaci and Reutenauer, acting on the free associative algebra, to a vector space of operators acting on all graded connected Hopf algebras. These operators are convolution products of certain involutions, which we view as hyperoctahedral variants of Patras's descent operators. We obtain the eigenvalues and multiplicities of all our new operators, as well as a basis of eigenvectors for a subclass akin to Adams operations. We outline how to apply this eigendata to study Markov chains, and examine in detail the case of card-shuffles with flips or rotations.
