Abstract
For a totally real number field and a nonarchimedean prime of lying above a prime number we introduce certain sheaf cohomology groups that intertwine the -tower of a quaternionic Hilbert modular variety associated to a quaternion algebra over that is split at and a -adically admissible representation of . Applied to infinitesimal -adic deformations of the local factor at of a cuspidal automorphic representation of this yields a natural construction of infinitesimal deformations of the Galois representation attached to .
