new results from complex dynamics

Henryk has a paper with a uniquess criteria for sexp(z), and I hope to eventually show the theta(z) uniqueness criteria I posted yesterday, , can be shown to be complete if both fixed points are repelling and theta(z) has a singularity.

So I guess I was right -- the strange fixpoint-reversal phenomenon probably simply means the continuation is impossible.

Are you calculating sexp(z), or slog(z)? I've started to make plots of slog(z) as well, for the bipolar solutions, inside the Shell Thron boundary. Also, as you point out, as you approach the second Shell Thron crossing, the singularities for sexp(z) in the upper half of the complex plane (rotating around eta counterclockwise) start to bunch up and get arbitrarily close to each other and the real axis.

I was calculating the fixed points to see how the sickel would behave at the boundary crossing, to see if it "exploded" or something weird like that.

How do you graph slog(z), anyway -- i.e. how do you handle all the branch cutting and so forth?
