## Rigid character groups, Lubin-Tate theory, and $(\phi,\Gamma)$-modules

##### Abstract:

The talk will describe joint work with L. Berger and B. Xie in which we build, for a finite extension L of $\Bbb{Q}_p$, a new theory of $(\phi,\Gamma)$-modules whose coefficient ring is the ring of holomorphic functions on the rigid character variety of the additive group $o_L$, resp. a "Robba" version of it.
