Abstract

Two explicit sets of solutions to the double shuffle equations modulo products were introduced by Ecalle and Brown respectively. We place the two solutions into the same algebraic framework and compare them. We find that they agree up to and including depth four but differ in depth five by an explicit solution to the linearized double shuffle equations with an exotic pole structure.

双shuffle方程模积的ecalle和brown极坐标解

Ecalle和Brown分别介绍了模积双混洗方程的两组显式解。我们把这两个解放在同一个代数框架中，并对它们进行比较。我们发现，通过具有奇异极点结构的线性化双洗牌方程的显式解，它们在深度4（包括深度4）上一致，但在深度5上不同。

期刊介绍： The Kyushu Journal of Mathematics is an academic journal in mathematics, published by the Faculty of Mathematics at Kyushu University since 1941. It publishes selected research papers in pure and applied mathematics. One volume, published each year, consists of two issues, approximately 20 articles and 400 pages in total. More than 500 copies of the journal are distributed through exchange contracts between mathematical journals, and available at many universities, institutes and libraries around the world. The on-line version of the journal is published at "Jstage" (an aggregator for e-journals), where all the articles published by the journal since 1995 are accessible freely through the Internet.
