Iwasawa invariants in residually reducible Hida families

Number Theory 2025-09-17 v2

Abstract

We study the variation of μ\mu-invariants of modular forms in a cuspidal Hida family in the case that the family intersects an Eisenstein family. We allow for intersections that occur because of "trivial zeros" (that is, because pp divides an Euler factor) as in Mazur's Eisenstein ideal paper, and pay special attention to the case of the 5-adic family passing through the elliptic curve X0(11)X_0(11).
