Dynamics on the space of harmonic functions and the foliated Liouville problem
R. Feres, A. Zeghib
We study here the action of subgroups of PSL(2,R) on the space of harmonic functions on the unit disc bounded by a common constant, as well as the relationship this action has with…

Rolling systems and their billiard limits
C. Cox, R. Feres, B. Zhao
Billiard systems, broadly speaking, may be regarded as models of mechanical systems in which rigid parts interact through elastic impulsive (collision) forces. When it is desired o…

Leafwise Holomorphic Functions
R. Feres, A. Zeghib
It is a well-known and elementary fact that a holomorphic function on a compact complex manifold without boundary is necessarily constant. The purpose of the present article is to…
