On the $\mu$ equals zero conjecture for the fine Selmer group in Iwasawa theory

Number Theory 2023-04-11 v3

Abstract

We study the Iwasawa theory of the fine Selmer group associated to certain Galois representations. The vanishing of the μ\mu-invariant is shown to follow in some cases from a natural property satisfied by Galois deformation rings. We outline conditions under which the μ=0\mu=0 conjecture is shown to hold for various Galois representations of interest.
