果冻传媒

Hello! I have finished my PhD under the supervision of Professor John SmillieLink opens in a new window, and now work at Kyushu University with . My new email address is richards.jordan.thomas.745 "at" m.kyushu-u.ac.jp.

I am interested in complex dynamics, in particular, the dynamics of complex H茅non maps.

Previously I studied my MMath at the University of Liverpool and undertook two projects supervised by . These projects concerned the dynamics of quadratic polynomials.

With Professor Smillie I studied complex dynamics in two dimensions. We are developing a new notion of external rays for H茅non maps which can be computed in Mathematica. We hope to show these rays converge to the more traditional notion of external rays. Using these rays we are investigating the work of Chris Lipa and hope to develop that into a more rigorous theory.

This notion of external rays leads to approximations of the H茅non Julia set. We can take a projection of the data we generate and produce pictures. An early version of such a picture is shown below. On the left is a SaddleDrop output due to Sarah Koch and the right shows the Mathematica output. More examples can be found hereLink opens in a new window.
