Multiplicative reduction and the cyclotomic main conjecture for $\mathrm{GL}_2$

Number Theory 2016-06-22 v1

Abstract

We show that the cyclotomic Iwasawa--Greenberg Main Conjecture holds for a large class of modular forms with multiplicative reduction at pp, extending previous results for the good ordinary case. In fact, the multiplicative case is deduced from the good case through the use of Hida families and a simple Fitting ideal argument.
