An alternative $\mathbb{Q}$-form of the cyclotomic double shuffle Lie algebra (2502.00742v1)
Published 2 Feb 2025 in math.NT and math.QA
Abstract: We present an alternative $\mathbb{Q}$-form for Racinet's cyclotomic double shuffle Lie algebra, inspired by the double shuffle relations among congruent multiple zeta values studied by Yuan and Zhao. Our main result establishes an invariance characterization theorem, demonstrating how these two $\mathbb{Q}$-forms can be reconstructed from each other under Galois action.
