Critical Locus for Complex Henon maps

Abstract:
For one dimensional maps, the dynamics of the map is to a large extent determined
by the orbits of the critical points. Complex Hénon maps are automorphisms,
and as such they do not have critical points. Critical loci, the sets of tangencies
between dynamically defined foliations/laminations often serve as a good analog of
the critical points.
We study the critical loci in the escape region, defined by
E. Bedford, J. Smillie and J. Hubbard. We give a description of the critical locus for
Hénon maps in an HOV region, the first description in the non-perturbative setting.
We also discuss the connection between the critical loci in different dynamically significant
regions and the monodromy of the critical locus. This is a joint work with R. Radu and R. Tanase.
