Recurrence of the twisted planar random walk
U. Haboeck
We show that the "twisted" planar random walk - which results by summing up stationary increments rotated by multiples of a fixed angle - is recurrent under diverse assumptions on…

Non-abelian extensions of minimal rotations
Ulrich Haboeck, Vyacheslav Kulagin
We consider continuous extensions of minimal rotations on a locally connected compact group X by arbitrary locally compact Lie groups and prove regularity (i.e. the existence of or…

Nilpotent extensions of minimal homeomorphisms
Gernot Greschonig, Ulrich Haboeck
In this paper we study topological cocycles for minimal homeomorphisms on a compact metric space. We introduce a notion of an essential range for topological cocycles with values i…
