The delta symbol is the key in solving many different prob-
lems in the analytic theory of numbers. In recent years this has been used to solve various sub-convexity problems for higher rank L-functions. This talk will be a brief report on some new progresses. In particular, I will mention the results obtained in recent joint works with Roman Holowinsky and Zhi Qi and Sumit Kumar and Saurabh Singh. |
