<p>I want to study representation of teichmuller space of surface of genus g in psl(2,R).
can you suggest any good references.</p>

<p>Given a hyperbolic surface S with geodesic boundary. Let a and b be two distinct simple closed geodesic boundaries. Does there exist a unique distance realizing geodesic in S?
(1) for S is a pair of pants.
(2) S is any hyperbolic surface with boundary. </p>

http://mathoverflow.net/questions/95829/distance-of-a-point-from-a-geodesic-on-hyperbolic-surfaceComment by Bidyut SankiBidyut Sanki2012-05-03T18:43:25Z2012-05-03T18:43:25Z@ Sam Nead, The motivation is the following: It is wellknown that given a geodesic $\gamma$ a point $p$ in hyperbolic plane then there is a unique geodesic from p to $\gamma$ meeting perpendicularly and realizes the distance from p to $\gamma$. So if we take hyperbolic surface instead of hyperbolic plane then what will happen.
@ Anton Petrunin Please provede a proof or reference for your answer. Thanks a lot http://mathoverflow.net/questions/95724/uniqueness-of-distance-realizing-geodesic-in-hyperbolic-surface/95728#95728Comment by Bidyut SankiBidyut Sanki2012-05-02T08:26:32Z2012-05-02T08:26:32Zwell, I have got an example of hyperbolic surface with boundary where more than one (at least two) distance realizing geodesics between two distinct geodesic boundaries will exist. I have a further question: Suppose p and q are two distance realizing geodesics between the boundary geodesics. Is it true that p and q are always disjoint? http://mathoverflow.net/questions/95640/distance-realizing-geodesics-in-hyperbolic-surfacesComment by Bidyut SankiBidyut Sanki2012-05-02T05:26:14Z2012-05-02T05:26:14Z@ Yemon choi..
