In this paper we prove that the $\mathcal{E}^\dagger_K$-valued cohomology, introduced in [9] is finite dimensional for smooth curves over Laurent series fields $k((t))$ in positive characteristic, and forms an $\mathcal{E}^\dagger_K$-lattice inside `classical' $\mathcal{E}_K$-valued rigid cohomology. We do so by proving a suitable version of the p-adic local monodromy theory over $\mathcal{E}^\dagger_K$, and then using an \'{e}tale pushforward for smooth curves to reduce to the case of $\mathbb…

Rigid cohomology over Laurent series fields III: Absolute coefficients and arithmetic applications
In this paper we investigate the arithmetic aspects of the theory of $\mathcal{E}_K^\dagger$-valued rigid cohomology introduced and studied in [11,12]. In particular we show that these cohomology
Rigid Cohomology over Laurent Series Fields
In this monograph, the authors develop a new theory of p-adic cohomology for varieties over Laurent series fields in positive characteristic, based on Berthelot's theory of rigid cohomology. Many
Finiteness of rigid cohomology with coefficients
We prove that for any field k of characteristic p>0, any separated scheme X of finite type over k, and any overconvergent F-isocrystal E over X, the rigid cohomology H^i(X, E) and rigid cohomology
Finiteness theorems for the cohomology of an overconvergent isocrystal on a curve
Abstract Let M be an overconvergent isocrystal on a smooth affine curve X / k over a perfect field of characteristic p > 0, realized as a module on a suitable lifting of X with connection. We give a
A p-adic local monodromy theorem
We produce a canonical filtration for locally free sheaves on an open p-adic annulus equipped with a Frobenius structure. Using this filtration, we deduce a conjecture of Crew on p-adic differential
More étale covers of affine spaces in positive characteristic
We prove that every geometrically reduced projective variety of pure dimension n over a field of positive characteristic admits a morphism to projective n-space, etale away from the hyperplane H at
