On a lifting of t-adic symmetric multiple zeta values
摘要
The t-adic symmetric multiple zeta value is a generalization of the symmetric multiple zeta value from the perspective of the Kaneko–Zagier conjecture. In this paper, we introduce a further generalization with a new parameter s, which we call the (s, t)-adic symmetric multiple zeta value. Then, the (s, t)-adic version of the t-adic double shuffle relations, duality and cyclic sum formula are established. A finite counterpart of the (s, t)-adic symmetric multiple zeta value is also discussed.
