Shishikura's proof established the the long-standing "hairiness" conjecture. The proof is very subtle, but here is a rough outline of the steps. |
In the cusp of the big cardioid, Shishikura found a sequence of
Misiurewicz points cn with |
By Tan-Lei's theorem,
regions in M around these cn have |
Every circle around every boundary point of the Mandelbrot set
encloses copies of the Mandelbrot set, and the cusps of these copies have regions with
