DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CAFAS/33/">I
 wasawa theory over imaginary quadratic fields for inert primes</a>\nby Ant
 onio Lei (Laval) as part of Columbia Automorphic Forms and Arithmetic Semi
 nar\n\n\nAbstract\nLet $p$ be a fixed odd prime and $K$ an imaginary quadr
 atic field where $p$ is inert. Let $f$ be an elliptic modular form with go
 od ordinary reduction at $p$. We discuss how the cyclotomic Iwasawa theory
  of the Rankin-Selberg product of $f$ and a $p$-non-ordinary CM form allow
 s us to study the Iwasawa theory of $f$ over the $\\mathbf{Z}_p^2$-extensi
 on of $K$. We make use of the plus and minus theory of Kobayashi and Polla
 ck as well as Euler systems built out of Beilinson--Flach elements. This i
 s joint work with Kazim Buyukboduk.\n
