I'm looking for references to applications of the Hairy ball theorem.
I already visited wikipedia and cited references, but I need a little more explanation in both meteorology and applications in computer graphics. If any other application would be excellent.
I've also read some questions on this site and some articles uploaded (an article of John Milnor for example), but none deals specifically with applications.
Maybe it's a bit difficult because I seek not know much about meteorology or computer graphics, but I'm just interested
Thanks for any help.
