Abstract

The Kaneko-Zagier conjecture states that finite and symmetric multiple zeta values satisfy the same relations. In the previous work with H.~Bachmann and Y.~Takeyama, we proved that the finite and symmetric multiple zeta value are obtained as an `algebraic' and `analytic' limit at q1q\rightarrow 1 of a certain truncated multiple harmonic qq-series, and studied its relations in order to give partial evidence of the Kaneko-Zagier conjecture. In this paper, we start with truncated multiple harmonic qq-series of level NN, which is a qq-analogue of the truncated colored multiple zeta value. We introduce our finite and symmetric colored multiple zeta values as an algebraic and analytic limit of the truncated multiple harmonic qq-series of level NN and discuss a higher level (or a cyclotomic) analogue of the Kaneko-Zagier conjecture.
