概要
A famous conjecture by R. Greenberg asserts that a modular 2-dimensional p-adic Galois representation of a cusp form of weight larger than or equal to 2 is indecomposable over the p-inertia group. I start with a survey of the known results and then describe a new case of indecomposability when the modular Galois representation is a deformation of an induced representation.
