Double zeta values and Picard-Fuchs equation

In this paper we will study the double zeta values $\zeta (k,m)$ using Picard-Fuchs equation. We will give a very efficient method to evaluate $\zeta (k,1)$ (resp. $\zeta (k,2)$) in terms of the products of zeta values $\zeta (2),\zeta (3),\cdots$ when $k$ is even (resp. odd), which admits immediate generalization to arbitrary double zeta values. Moreover, this method provides new insights into the nature of double zeta values, which further can be generalized to arbitrary multiple zeta values.
