Comparing anticyclotomic Selmer groups of positive coranks for congruent modular forms -- Part II

Abstract

We study the Selmer group associated to a $p$-ordinary newform $f\in S_{2r}({\Gamma }_0(N))$ over the anticyclotomic ${\mathbb{Z}}_p$-extension of an imaginary quadratic field $K/\mathbb{Q}$. Under certain assumptions, we prove that this Selmer group has no proper $\Lambda$-submodules of finite index. This generalizes work of Bertolini in the elliptic curve case. We also offer both a correction and an improvement to an earlier result on Iwasawa invariants of congruent modular forms by the present authors.
