A Vector Supersymmetry Killing the Infrared Singularity of Gauge Theories in Noncommutative Space

open access: yes, 2006
We show that the "topological BF-type" term introduced by Slavnov in order to cure the infrared divergences of gauge theories in noncommutative space can be characterized as the consequence of a new symmetry.

Extremal properties of the set of vector-valued Banach limits

open access: yesOpen Mathematics, 2015
In this manuscript we find another class of real Banach spaces which admit vector-valued Banach limits different from the classes found in [6, 7]. We also characterize the separating subsets of ℓ∞(X).

Sublinear and continuous order-preserving functions for noncomplete preorders

open access: yes, 2002
We characterize the existence of a nonnegative, sublinear and continuous order-preserving function for a not necessarily complete preorder on a real convex cone in an arbitrary topological real vector space.

Extending Topological Abelian Groups by the Unit Circle

open access: yesAbstract and Applied Analysis, 2013
A twisted sum in the category of topological Abelian groups is a short exact sequence 0→Y→X→Z→0 where all maps are assumed to be continuous and open onto their images. The twisted sum splits if it is equivalent to 0→Y→Y×Z→Z→0.
