# Smeared hair and black holes in three-dimensional de Sitter spacetime

@article{Park2008SmearedHA, title={Smeared hair and black holes in three-dimensional de Sitter spacetime}, author={Mu-In Park}, journal={Physical Review D}, year={2008}, volume={80}, pages={084026} }

It is known that there is no three-dimensional analog of de Sitter black holes. I show that the analog does exist when non-Gaussian (i.e., ring-type) smearings of point matter hairs are considered. This provides a new way of constructing black hole solutions from hairs. I find that the obtained black hole solutions are quite different from the usual large black holes in that there are (i) large to small black hole transitions which may be considered as inverse Hawking-Page transitions and (ii…
