On evaluation formulas for double <i>L</i>-values
On evaluation formulas for double <i>L</i>-values
In this paper, we give some evaluation formulas for the values of double L -series of Tornheim's type, in terms of the Dirichlet L -values and the Riemann zeta values at positive integers. As special cases, these give the formulas for double L -values given by Terhune.
