A cohomological obstruction in higher dimensional Chern--Simons gauge theories
Marcella Palese, Ekkehart Winterroth
We study a set of cohomology classes which emerge in the cohomological formulations of the calculus of variations as obstructions to the existence of (global) solutions of the Eule…

Variational cohomology and topological solitons in Yang-Mills-Chern-Simons theories
Ekkehart Winterroth
In cohomological formulations of the calculus of variations obstructions to the existence of (global) solutions of the Euler-Lagrange equations can arise in principle. It seems, ho…
