Abstract
We compute the pp-adic geometric étale cohomology of the coverings of the Drinfeld half-plane, and we show that, if the base field is Qp\mathbf {Q}_p, this cohomology encodes the pp-adic local Langlands correspondence for 22-dimensional de Rham representations (of weight 00 and 11).
期刊介绍:
All articles submitted to this journal are peer-reviewed. The AMS has a single blind peer-review process in which the reviewers know who the authors of the manuscript are, but the authors do not have access to the information on who the peer reviewers are.
This journal is devoted to research articles of the highest quality in all areas of pure and applied mathematics.
