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…

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…
