This note establishes a transition formula for Iwasawa invariants in modular forms, removing a previous condition for similar modular varieties.
Let be an odd prime, and suppose that and are weight two newforms sharing the same irreducible Galois representation modulo . We establish a transition formula relating the ‐invariants and in the case where their underlying modular varieties have the same dimension. For abelian extensions , this essentially removes the condition present in the earlier work of Greenberg–Vatsal and Emerton–Pollack–Weston.
