NCN2 - New connections in number theory and physics

I will write down the “massive” SL(2) Kronecker-Eisenstein series from arXiv:1910.02745 (with Bringmann and Gannon), and briefly summarize some work in progress with Daniel Persson on “massive” theta lifts. I will try to explain why I believe that “massive deformations” exist much more broadly than for SL(2) (“Kaluza-Klein reduction” in physics). More importantly, I think it would be fun to discuss what “mass” means (or should mean?) to mathematicians, for example in representation theory.
