We know at least two ways to generalize multiple zeta(-star) values, or MZ(S)Vs for short, which are q-analogue and t-interpolation. The q-analogue of MZ(S)Vs, or qMZ(S)Vs for short, was introduced by Bradley, Okuda and Takeyama, Zhao, etc. On the other hand, the polynomials interpolating MZVs and MZSVs using a parameter t were introduced by Yamamoto. We call these t-MZVs.In this paper, we consider such two generalizations simultaneously, that is, we compose polynomials, called t-qMZVs, interpolating qMZVs and qMZSVs using a parameter t which are reduced to q xA0;MZVs as t=0t=0, to q xA0;MZSVs as t=1t=1, and to t xA0;-MZVs as q→1q→1. Then we prove Kawashima type relation, cyclic sum formula and Hoffman type relation for t-qMZVs.
