Abstract

We prove a potentially automorphy theorem for suitable Galois representations ΓF+ → GSpin2n+1(\mathbbFp) and ΓF+ → GSpin2n+1(ℚp), where ΓF+ is the absolute Galois group of a totally real field F+. We also prove results on solvable descent for GSp2n(\mathbbAF+) and use these to put representations ΓF+ → GSpin2n+1(ℚp) into compatible systems of GSpin2n+1(ℚ)-valued representations.
