Pseudo-rotations of the open annulus
F. Béguin, S. Crovisier, F. Le Roux
In this paper, we study pseudo-rotations of the open annulus, \emph{i.e.} conservative homeomorphisms of the open annulus whose rotation set is reduced to a single irrational numbe…

Pseudo-rotations of the closed annulus : variation on a theorem of J. Kwapisz
Sylvain Crovisier, Francois Beguin, Frederic Le Roux +1
Consider a homeomorphism h of the closed annulus S^1*[0,1], isotopic to the identity, such that the rotation set of h is reduced to a single irrational number alpha (we say that h…
