The Emerton--Gee stack of rank one $(\varphi,Γ)$-modules [PDF]

open access: yesDoc. Math. 29 (2024), no. 3, 733--746, 2022
We give a classification of rank one $(\varphi,\Gamma)$-modules with coefficients in a $p$-adically complete $\mathbf{Z}_p$-algebra. As a consequence, we obtain a new proof of Proposition 7.2.17 in {arXiv:1908.07185}, which gives an explicit description of the Emerton--Gee stack of $(\varphi,\Gamma)$-modules in the rank one case.
