Absence of twisting for non-trivial discrete torsion
Primoz Moravec
We study discrete torsion for the --torus with finite symmetry group from the Dijkgraaf--Witten viewpoint. A class in assigns a phase to each flat --bundle,…

Quasi-affine and quasi-quadratic maps of groups with non-abelian targets
Primoz Moravec
It is shown that the middle quasi-homomorphisms of Fujiwara and Kapovich are precisely constant perturbations of quasi-homomorphisms. Quasi-polynomial maps are defined and their co…
