Abstract

The construction of the $p$-adic local Langlands correspondence for $\mathrm {GL}_2(\mathbf {Q}_p)$ uses in an essential way Fontaine’s theory of cyclotomic $(\varphi ,\Gamma )$-modules. Here cyclotomic means that $\Gamma = \mathrm {Gal}(\mathbf {Q}_p(\mu _{p^\infty })/\mathbf {Q}_p)$ is the Galois group of the cyclotomic extension of $\mathbf {Q}_p$. In order to generalize the $p$-adic local Langlands correspondence to $\mathrm {GL}_2(L)$, where $L$ is a finite extension of $\mathbf {Q}_p$, it seems necessary to have at our disposal a theory of Lubin-Tate $(\varphi ,\Gamma )$-modules. Such a generalization has been carried out to some extent, by working over the $p$-adic open unit disk, endowed with the action of the endomorphisms of a Lubin-Tate group. The main idea of our article is to carry out a Lubin-Tate generalization of the theory of cyclotomic $(\varphi ,\Gamma )$-modules in a different fashion. Instead of the $p$-adic open unit disk, we work over a character variety, that parameterizes the locally $L$-analytic characters on $o_L$. We study $(\varphi ,\Gamma )$-modules in this setting, and relate some of them to what was known previously.
