Eisenstein series twisted by modular symbols for the group $\SL _{n}$Authors: Dorian Goldfeld and Paul E. Gunnells
Author institution: Columbia University, and Rutgers University
Summary: We define Eisenstein series twisted by modular symbols for the group $\operatorname{SL} _{n}$, generalizing a construction of the first author \cite{goldfeld1, goldfeld2}. We show that, in the case of series attached to the minimal parabolic subgroup, our series converges for all points in a suitable cone. We conclude with examples for $\operatorname{SL} _{2}$ and $\operatorname{SL} _{3}$.
