Global quadratic units and Hecke algebras
Documenta mathematica, Tome 3 (1998), pp. 273-284
Let {ρp}p be a compatible system of two dimansional p-adic Galois representations attached to a cusp form of Neben type (D)(D>0). We shall give an exact criterion, in terms of the fundamental unit ε of Q(D), determining primes p for which the image of ρpmodp is dihedral. Then we shall state a conjecture which gives an explicit description of the universal p-ordinary deformation ring of such mod p dihedral representations.
