Rigid character groups, Lubin-Tate theory, and \((\varphi,\Gamma)\)-modules Schneider, Peter


The talk will describe joint work with L. Berger and B. Xie in which we build, for a finite extension \(L\) of \(\mathbb{Q}_p\), a new theory of \((\varphi,\Gamma)\)-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.
