Abstract:
Some particular multiple zeta values or sums of multiple zeta value can be expressed as integrals in one or two variables. It provided a way to reprove theorems such as sum relation or the more general restricted sum formula of multiple zeta values. Based on the representation of the iterated integral of the n-tail of the multiple zeta value, the double tails of multiple zeta values was introduced and studied by Akhilesh. Then Seki and Yamamoto introduced the connected sum in order to give a new proof of the Ohno relation for q-analog of multiple zeta values. In this talk, we establish a duality relation among the generalized q-connected sum. The proof of such duality relies only on a crucial summation-identity, together with some of its consequences. Then we present the sum formula of n-tail of q-multiple zeta values and use the similar argument to reprove the well-known q-restricted sum formula of q-multiple zeta values.
