Uniform bounds and ultraproducts of cycles
Lars Brünjes, Christian Serpé
This paper is about the question whether a cycle in the l-adic cohomology of a smooth projective variety over the rational numbers, which is algebraic over almost all finite fields…
Etale and motivic cohomology and ultraproducts of schemes
Lars Brünjes, Christian Serpé
This paper is a continuation of the authors article "Enlargements of schemes" (Log. Anal.1 (2007), no. 1, 1-60) We mainly study the behaviour of etale cohomology, algebraic cycles…
Nonstandard model categories and homotopy theory
Lars Brünjes, Christian Serpé
In order to apply nonstandard methods to questions of algebraic geometry we continue our investigation from "Enlargements of categories" (Theory Appl. Categ. 14 (2005), No. 16, 357…
Nonstandard Etale Cohomology
Lars Brünjes, Christian Serpé
A lot of good properties of etale cohomology only hold for torsion coefficients. We use "enlargement of categories" as developed in http://arxiv.org/abs/math.CT/0408177 to define a…
