I spent time working with cubic mappings. With two critical points, there are Julia sets that consist of infinitely many disconnected components that are still locally connected, corresponding two one critical point escaping and one falling into one of the basins of attraction.
<br>Of course that was about 15 years ago, and I haven't really kept up. Too much time keeping up with software. <br><br><div><span class="gmail_quote">On 12/16/06, <b class="gmail_sendername">Jacques Carette</b> <<a href="mailto:email@example.com">
