DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UBC_NTS/6/">
 Arithmetic of theta liftings</a>\nby Yusheng Lee (Columbia University) as 
 part of UBC (online) Number Theory Seminar\n\n\nAbstract\nWe discuss the i
 ntegrality of theta liftings of anti-cyclotomic characters to a definite u
 nitary group $\\mathrm{U}(2)$ of two variables. This will allow us to cons
 truct a Hida family of the theta liftings and relate the congruence module
  of which to an anti-cyclotomic $p$-adic L-function. The result is an inpu
 t to Urban's construction of Euler systems.\n\nJoin Zoom Meeting\nhttps://
