Original Announcement
This workshop will be devoted to connections between automorphic forms, algebraic cycles, and intersection theory. Many phenomena in automorphic forms have interesting analogues in algebraic or arithmetic geometry. One key example is provided by Kudla and KudlaMillsonâ€™s generating series of special cycles, which are geometric analogues of theta series. Another is the GanGrossPrasad period integral, which also has an arithmetic analogue in terms of intersections of special cycles. The workshopâ€™s goal is to further develop instances of these known analogies, and to explore new ones, involving novel tools like derived algebraic geometry.
The main topics for the workshop are

Connections between periods of automorphic forms and the arithmetic geometry of Shimura varieties and their function field analogues.

Modularity results for generating series of algebraic cycles.

Applications of derived algebraic geometry to intersection theory.
