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

We study ``change of weights'' maps between loci of the stack of (, ) -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 (, ) -modules geometrically. The motivation is to investigate translations of locally analytic representations under the categorical p-adic Langlands correspondence.
