For a rational prime p � 3 we consider p-ordinary, Hilbert modular newforms f of weight k � 2 with associated p-adic Galois representations �f and mod pn reductions �f;n. Under suitable hypotheses on the size of the image, we use deformation theory and modularity lifting to show that if the restrictions of �f;n to decomposition groups above p split then f has a companion form g modulo pn (in ...
