Rational Maps from Quotient Maps of Finite Kleinian Groups and Their Julia Sets
Quotient maps of finite Kleinian groups are rational maps with two or three critical values. They are also called rational maps with half symmetries. We explore some oneparameter families of such maps with a smilar classification of Julia sets in the oneparameter families of singularly perturbed monomials investigated by Devaney and his collaborators. This is joint work with Francisco G. Jimenez and Oleg Muzician.

Trees of Spheres and Berkovich Spaces
In the world of complex dynamics on the Riemann sphere, we study the action of complex rational maps of a given degree modulo the natural action by conjugacy of the group of Mobius transformations. As the quotient space is not compact, one is interested in giving a good compactification of this space that underlines some interesting dynamical behavior. For this, two tools from algebraic geometry have been introduced: the DeligneMumford compactification of the moduli space of stable curves and Berkovich spaces. I will explain the vocabulary used in my thesis to deal with the first tool and will compare it to the second one. No prior knowledge of either of these topics will be assumed.
