Semigroup models for discrete holomorphic iteration in the unit disc
Argyrios Christodoulou, Konstantinos Zarvalis
The main goal of this article is to develop a technique that allows us to partially embed the orbit of any holomorphic self-map of the disc, into a semigroup which captures the…
A note on the boundary dynamics of holomorphic iterated function systems
Argyrios Christodoulou
We consider the boundary dynamics of iterated function systems of holomorphic self-maps of the unit disc. Our main result provides a sufficient condition which guarantees that the…
Monotonicity properties of hyperbolic projections in holomorphic iteration
Argyrios Christodoulou, Konstantinos Zarvalis
We consider hyperbolic projections of orbits of holomorphic self-maps of the unit disc, onto curves landing on the unit circle with a given angle. We show that under certain, neces…
Symmetrization and the rate of convergence of semigroups of holomorphic functions
Dimitrios Betsakos, Argyrios Christodoulou
Let , , be a semigroup of holomorphic self-maps of the unit disk . Let be its Koenigs domain and be its Denjoy-Wolff point…
Self-projective sets
Argyrios Christodoulou, Natalia Jurga
Self-projective sets are natural fractal sets which describe the action of a semigroup of matrices on projective space. In recent years there has been growing interest in studying…
Random iteration on hyperbolic Riemann surfaces
Marco Abate, Argyrios Christodoulou
Let be a sequence of holomorphic self-maps of a hyperbolic Riemann surface . In this paper we shall study the asymptotic behavior of the sequences obtained by iterativ…
