Kida's formula and congruences

Doc. Math. (Bielefeld) Extra Vol. John H. Coates' Sixtieth Birthday, 615-630 (2006)

Summary

We consider a generalization of a result of Kida in classical Iwasawa theory which relates Iwasawa invariants of $p$-extensions of number fields. In this paper, we consider Selmer groups of a general class of Galois representations which includes the case of $p$-ordinary Hilbert modular forms and $p$-supersingular modular forms.
