DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NTBU/10/">On
  higher regulators of Picard modular surfaces</a>\nby Linli Shi (Universit
 y of Connecticut) as part of Boston University Number Theory Seminar\n\nLe
 cture held in CDS Room 365 in Boston University.\n\nAbstract\nThe Birch an
 d Swinnerton-Dyer conjecture relates the leading coefficient of the L-func
 tion of an elliptic curve at its central critical point to global arithmet
 ic invariants of the elliptic curve. Beilinson’s conjectures generalize 
 the BSD conjecture to formulas for values of motivic L-functions at non-cr
 itical points. In this talk\, I will relate motivic cohomology classes\, w
 ith non-trivial coefficients\, of Picard modular surfaces to a non-critica
 l value of the motivic L-function of certain automorphic representations o
 f the group GU(2\,1).\n
