Abstract

Based on Hopf algebra of rooted trees introduced by Connes and Kreimer, we construct a class of linear maps on noncommutative polynomial algebra in two indeterminates, namely rooted tree maps. We also prove that their maps induce a class of relations among multiple zeta values.

Keywords

Hopf algebra of rooted trees, noncommutative polynomial algebra, multiple zeta values, quasi-derivation relation, Kawashima’s relation
