A note on cohomology and algebraic geometric codes on the curves over rings

Annals of the West University of Timisoara: Mathematics and Computer Science
Let A be a local Artinian ring with residue field k(A). Let X be a curve over A and let be X′ = X ×spec A spec k(A) the fiber of X over k(A). Consider ℒ an invertible sheaf on X and ℒ ′ = ϕ*ℒ ∈ Pic(X′), where ϕ : X′ → X is the natural map.

The Topology of Spaces of Polygons [PDF]

, 2011
We study the topology of spaces of polygons in Euclidean space, viewed up to translations. The main results concern the structure of the homology groups and of the cohomology rings of the spaces.

Integral Monsky-Washnitzer and overconvergent de Rham-Witt cohomology

, 2018
I will talk on a recent result and possible applications concerning the comparison between integral Monsky-Washnitzer cohomology and overconvergent de Rham-Witt cohomology for smooth and affine schemes. This extends work of Davis and Zureick-Brown. Joint
