DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCSBsga/23/"
 >Eisenstein intersection points on the Hilbert Eigenvariety</a>\nby Adel B
 etina (University of Vienna) as part of UCSB Seminar on Geometry and Arith
 metic\n\n\nAbstract\nIn this talk\, we will report a joint work with M. Di
 mitrov and S.C. Shih  in which we study the local geometry of the Hilbert 
 Eigenvariety at an intersection point between an Eisenstein component and 
 the cuspidal locus. As applications\, we show the non-vanishing of certain
  Katz $p$-adic $L$-functions at $s=0$ and give a new proof of the Gross-St
 ark conjecture in the rank one case.\n
