Saeed Zakeri's Research

My main area of reseach is dynamical systems, especially holomorphic dynamics. I also have strong interests in complex analysis, Riemann surfaces, (trans)quasiconformal mappings, hyperbolic geometry and Kleinian groups, and geometric theory of foliations and laminations.

My publications on Google Scholar.

The following is a list of my publications in reverse chronological order:
