Abstract: We bound a short second moment average of the L-function of a GL(3) Hecke-Maass cusp form. This yields a t-aspect subconvexity bound and improves upon the earlier works. The main tools used are Duke-Friedlander-Iwaniec’s circle method, stationary phase analysis and bounds on exponential sums due to Adolphson and Sperber obtained by their extension of Dwork’s cohomology theory. This is a joint work with Ritabrata Munshi and Wing Hong Leung. |
