Geodesic length functions
and Teichm\"uller spaces
Feng Luo
Abstract.
Given a compact orientable surface
$\Sigma$, let
$\Cal S(\Sigma)$ be the set of isotopy classes of essential simple closed
curves in $\Sigma$. We determine a complete set of relations for a function
from $\Cal S(\Sigma)$ to $\bold R$ to be the geodesic length function of a hyper
bolic metric
with geodesic boundary on $\Sigma$. As a consequence, the Teichm\"uller
space of hyperbolic metrics with geodesic boundary on $\Sigma$
is reconstructed from an intrinsic combinatorical structure on $\Cal S(\Sigma)$.
This also gives a complete description of the image of Thurston's
embedding of the Teichm\"uller space.
