$(\varphi,Γ)$-modules over relatively discrete algebras

Abstract: In this paper, we will consider $(\varphi,\Gamma)$-modules over rings which are "combinations of discrete algebras and affinoid $\mathbb{Q}_p$-algebras", and prove basic results such as the existence of a fully faithful functor from the category of Galois representations, the deperfection of $(\varphi,\Gamma)$-modules over perfect period rings, and the dualizability of the cohomology of $(\varphi,\Gamma)$-modules. This work is motivated by the categorical $p$-adic Langlands correspondence for locally analytic representations, as proposed by Emerton-Gee-Hellmann, and the $GL_1$ case, as formulated and proved by Rodrigues Jacinto-Rodr\'iguez Camargo.
