SUMMARY:The concept of "mass" according to physicists and mathematicians -

DESCRIPTION:I will write down the "massive" SL(2) Kronecker-Eisenstein ser
 ies from arXiv:1910.02745 (with Bringmann and Gannon)\, and briefly summar
 ize some work in progress with Daniel Persson on "massive" theta lifts. I 
 will try to explain why I believe that "massive deformations" exist much m
 ore broadly than for SL(2) ("Kaluza-Klein reduction" in physics). More imp
 ortantly\, I think it would be fun to discuss what "mass" means (or should
  mean?) to mathematicians\, for example in representation theory.
