Bogomolov property conjecture for modular Galois representations

Less than 1 year old · traced to

Let f∈Sk(Γ1(N))f\in S_k(\Gamma_1(N)) be a normalized eigenform, and let ρf,v\rho_{f,v} denote its Galois representation at a non-Archimedean place vv and ρ^f\widehat{\rho}_f the product of these representations. For a representation, property (B) means that the field fixed by its kernel has the Bogomolov property. Modular representation conjecture. Then:

(a) for every non-Archimedean place v, ρf,v has property (B);\text{(a) for every non-Archimedean place }v,\ \rho_{f,v}\text{ has property (B);} (b) ρ^f has property (B).\text{(b) }\widehat{\rho}_f\text{ has property (B).}

The conjecture is motivated by Habegger's theorem and known results for modular representations; part (b) implies part (a), but the converse is not immediate because property (B) is not preserved under composita. Both assertions remain open according to the supplied status information.
