Ce Xu, Jianqiang Zhao

AI总结:

本文建立卷积多重zeta值及其变体的显式关系,利用迭代积分推导公式,定义二级类比并推广积分-级数恒等式至多重polylogarithm和多重混合值,最后通过图形表示研究多重积分。

摘要:

Kaneko和Yamamoto在2016年前后引入了多重zeta值(MZVs)的一种卷积变体。在本文中,我们首先利用迭代积分建立涉及这些值及其交错版本的若干显式公式,这使我们能够推导出多重polylogarithm(MPL)函数的一些显式关系。接下来,我们定义卷积多重$t$-值和多重混合值(MMVs)作为卷积MZVs的二级类比,并且类似于卷积MZVs,使用迭代积分来寻找这些二级类比的一些关系。然后我们考虑参数化MPLs和参数化多重调和(星)和,并将Kaneko-Yamamoto的MZVs的“积分-级数”恒等式推广到MPLs和MMVs。最后,我们通过将Yamamoto的图形表示推广到多重标记偏序集来研究MPLs和MMVs的多重积分。

英文摘要:

Kaneko and Yamamoto introduced a convoluted variant of multiple zeta values (MVZs) around 2016. In this paper, we will first establish some explicit formulas involving these values and their alternating version by using iterated integrals, which enable us to derive some explicit relations of the multiple polylogarithm (MPL) functions. Next, we define convoluted multiple $t$-values and multiple mixed values (MMVs) as level two analogs of convoluted MZVs, and, similar to convoluted MZVs, use iterated integrals to find some relations of these level two analogs. We will then consider the parametric MPLs and the parametric multiple harmonic (star) sums, and extend the Kaneko-Yamamoto's "integral-series" identity of MZVs to MPLs and MMVs. Finally, we will study multiple integrals of MPLs and MMVs by generalizing Yamamoto's graphical representations to multiple-labeled posets.
