Permutation statistics related to a class of noncommutative symmetric functions and generalizations of the Genocchi numbers

Florent Hivert, Jean-Christophe Novelli, Lenny Tevlin, Jean-Yves Thibon

摘要:

我们证明了第三作者[L. Tevlin,Proc. FPSAC'07,Tianjin]在非交换对称函数的两种新基上:带状基的转移阵具有非负整系数.这是通过两个组合值的统计排列和包装的话,推广的组合Genocchi数。

英文摘要:

We prove conjectures of the third author [L. Tevlin, Proc. FPSAC'07, Tianjin] on two new bases of noncommutative symmetric functions: the transition matrices from the ribbon basis have nonnegative integral coefficients. This is done by means of two composition-valued statistics on permutations and packed words, which generalize the combinatorics of Genocchi numbers.
