Geometric translations of (φ,Γ)-modules for GL₂(Qₚ)

We study ``change of weights'' maps between loci of the stack of (φ,Γ)-modules over the Robba ring with integral Hodge-Tate-Sen weights. We show that in the GL₂(Qₚ) case these maps can realize translations of (φ,Γ)-modules geometrically. The motivation is to investigate translations of locally analytic representations under the categorical p-adic Langlands correspondence.
