Hedgehog Awards




MR1088326
(92c:83013) Williams,
J.
G. Combed hedgehog
kink metric in (2+1)
dimensions.
Gen. Relativity Gravitation
23
(1991),
no. 2, 181–187. Also, the famous theorem of Poincare from 1885 states that it is impossible to comb a hedgehog. Unfortunately, to the great annoyance of hedgehogs, this prominent result became known under the vulgar name of the Hairy Ball Theorem (uffa!...) so it does not qualify. 

Pat
Cladis, Liquid
Crystals
and
the
Drunken Hedgehog, Physics World, 5 (1992)
22. Apparently, the LC monitor you
are probably looking at right now can be a home to a whole
universe of hedgehogs:
Hedgehogs Radial and Hyperbolic and less orderly Metastable and Drunken ones... :)
