Modularity of trianguline Galois representations

Number Theory 2023-11-17 v3

Abstract

We use the theory of trianguline (φ,Γ)(\varphi,\Gamma)-modules over pseudorigid spaces to prove a modularity lifting theorem for certain Galois representations which are trianguline at pp, including those with characteristic pp coefficients. The use of pseudorigid spaces lets us construct integral models of the trianguline varieties of [BHS17b], [Che13] after bounding the slope, and we carry out a Taylor--Wiles patching argument for families of overconvergent modular forms. This permits us to construct a patched quaternionic eigenvariety and deduce our modularity results.
