内容	The ℓ-adic Galois analogue of multiple zeta values and polylogarithms are defined using noncommutative 1-cocycles arising from the Galois action on the pro-ℓ etale fundamental groupoid of the projective line minus three points with rational base points. These objects were first introduced by Wojtkowiak and are closely related to the Soule character, along with its polylogarithmic refinement — the generalized Soule character — formulated by Nakamura-Wojtkowiak. In this talk, we will discuss relations among ℓ-adic Galois multiple zeta values and functional equations of ℓ-adic Galois polylogarithms.
