Critical values of (higher) derivatives of twisted elliptic L-functions
Hershy Kisilevsky (Concordia University)
Let L(E/Q,s) be the L-function of an elliptic curve E defined over the rational field Q. We examine special values of the r-th derivatives, L^(r)(E,1,χ), of twists by Dirichlet characters χ of L(E/Q,s) when L(E,1,χ)= . . . = L^(r-1)(E,1,χ)=0.
