DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCSBsga/4/">
 Congruence ideal associated to Yoshida lifts</a>\nby Bharath Palvannan (NC
 TS\, Taiwan) as part of UCSB Seminar on Geometry and Arithmetic\n\n\nAbstr
 act\nThis talk will be a report of work in progress with Ming-Lun Hsieh. I
 n analogy with the study of the congruences involving Hecke eigenvalues as
 sociated to Eisenstein series\, we study congruences involving p-adic fami
 lies of Hecke eigensystems associated to the space of Yoshida lifts of two
  Hida families. Our goal is to show that under suitable assumptions\, the 
 characteristic ideal of the dual Selmer group associated to the Rankin--Se
 lberg product of the Hida families is contained in the corresponding congr
 uence ideal. We also discuss connections between pseudo-cyclicity of the d
 ual Selmer group and higher codimension Iwasawa theory.\n
