仿射分圆Yokonuma-Hecke代数上的Markov迹

Markov traces on affine and cyclotomic Yokonuma-Hecke algebras

Maria Chlouveraki, Loïc Poulain d'Andecy

摘要:

本文定义并研究了仿射分圆Yokonuma-Hecke代数。这些代数推广在同一时间的Ariki小池和仿射Hecke代数和横沼-Hecke代数。我们研究了这些代数的表示论,并构造了它们的几个基。然后,我们展示了如何定义马尔可夫轨迹,我们反过来用它来构建不变量的框架和经典的结在固体环面。最后,我们研究了分圆Yokonuma-Hecke代数上的零参数Markov迹,并确定了该迹的Schur元。

英文摘要:

In this article, we define and study the affine and cyclotomic Yokonuma-Hecke algebras. These algebras generalise at the same time the Ariki-Koike and affine Hecke algebras and the Yokonuma-Hecke algebras. We study the representation theory of these algebras and construct several bases for them. We then show how we can define Markov traces on them, which we in turn use to construct invariants for framed and classical knots in the solid torus. Finally, we study the Markov trace with zero parameters on the cyclotomic Yokonuma-Hecke algebras and determine the Schur elements with respect to that trace.
