Delta symbols and the subconvexity problem November 2 to November 6, 2020 American Institute of Mathematics, San Jose, CA Organizers: Roman Holowinsky, Paul Nelson, and Matthew Young Description: This workshop, sponsored by AIM and the NSF, will be devoted to the understanding of novel delta methods that have had applications to subconvexity problems in recent years. Notably, Munshi has produced subconvexity bounds for twists of $GL_3$ automorphic forms. Deadline: July 15, 2020 Details: http://aimath.org/workshops/upcoming/deltasubconvexV
