Henon Map Real Parameter Space by Karl Papadantonakis
The following images all created using SaddleDrop
key (above)
yellow: all critical points escaped
red or black: some critical points did not escape (approximately the horseshoe locus compliment)
black: no critical point escaped (approximately the connectedness locus)
gray curve: outline of period 1 sink locus (should be painted red inside)
white: inability to follow critical points continuously
below: same region, with more holes in horseshoe locus revealed
below: connectedness locus (black in top image) zoomed around c=-2, a=0 (the tip of the Mandelbrot set). We have named the large revealed island "Australia"
Below: blowup of Australia
