Minimal assumption derivation of a Bell-type inequality

Gerd Grasshoff, Samuel Portmann, Adrian Wuethrich

John Bell showed that a big class of local hidden-variable models stands in conflict with quantum mechanics and experiment. Recently, there were suggestions that empirical adequate…

The Vertex Function in Perturbative QCD and -Meson Mass Effects

A. Ali, A. Ya. Parkhomenko

The effective vertex function (EVF) is calculated in the QCD hard-scattering approach, taking into account the -meson mass. We work in the approxim…

Homology of powers of regular ideals

Samuel Wüthrich

For a commutative ring R with an ideal I, generated by a finite regular sequence, we construct differential graded algebras which provide R-free resolutions of I^s and of R/I^s for…

Maximal (sequentially) compact topologies

Hans-Peter A. Künzi, Dominic van der Zypen

We revisit the known problem whether each compact topology is contained in a maximal compact topology and collect some partial answers to this question. For instance we show that e…

Topological obstructions to graph colorings

Eric Babson, Dmitry N. Kozlov

For any two graphs and Lovász has defined a cell complex having in mind the general program that the algebraic invariants of these complexes should provide obstr…
