Anticyclotomic Iwasawa invariants and congruences of modular forms
Pages: 499 – 530
The main purpose of this article is to examine how congruences between Hecke eigensystems of modular forms affect the Iwasawa invariants of their anticyclotomic $p$-adic $L$-functions. We apply Greenberg–Vatsal and Emerton–Pollack–Weston’s ideas on the variation of Iwasawa invariants under congruences to the anticyclotomic setting. As an application, we establish infinitely many new examples of the anticyclotomic main conjecture for modular forms, which are not treated by Skinner–Urban’s work. An explicit example is given.
