Abstract |
In this talk, I will give an introduction about our program
to understand the parameter spaces of dynamical systems generated by
meromorphic functions with finitely many singular values. I will give
a description of the bifurcation diagram of the tangent family and the
parameter space of meromorphic functions with precisely two finite
asymptotic values and one attracting fixed point. It represents a step
beyond the previous work for the parameter space of quadratic
polynomials and the parameter space of degree two rational functions.
In particular, for the parameter space of degree two rational maps
that have analogous constraints: two critical values and an attracting
fixed point. What is interesting and promising for pushing the general
program even further, is that, despite the presence of the essential
singularity and infinite degree for the covering, our family of
meromorphic functions exhibits a dynamic structure as similar as one
could hope to the rational case, and that the philosophy of the
techniques used in the rational case could be adapted. This talk is
based on a recent joint work with Tao Chen and Linda Keen.
