Outline of Final Research Achievements |
In this research, we studied multiple zeta values (MZV's) over the rational function field K over a finite field, and the Carlitz multiple polylogarithms (CMPL's) (joint work with Chieh-Yu Chang). More precisely, we showed that the infinite/v-adic CMPL's are related to some coordinate of the logarithm of an explicitly constructed t-module at a special point, where v is a finite place of K. By using this formula, we proved that an infinite-adic CMPL at an algebraic point is Eulerian if and only if the corresponding v-adic CMPL's at algebraic points are zero. Moreover, we defined v-adic MZV's and proved that v-adic MZV's satisfy the linear relations that their corresponding infinite-adic MZV's satisfy. We also defined finite CMPL's, and showed that each finite MZV over K is a K-linear combination of finite CMPL's at integral points.
