view. Let us explain what we mean by this. First recall that the … Our goal is to both explain and refine the Breuil–Mézardconjecture in these terms, by identifying the irreducible components of the various rings involved, in representation-theoretic terms, as well as to determine their multiplicities. To be somewhat more precise, after recalling some background material in ğ 2, in ğ 3 we consider the case of two-dimensional representations of GQp , as … Finally, in ğ 5, we …
Let unitary groups. We deduce an unconditional result in the case of two-dimensional potentially Barsotti–Tate representations.
