introduction
review of hyperbolic geometry
- horocycle
- exponentiated hyperbolic distances between horocycles drawn around vertices of a polygon with geodesic sides and cusps at the vertices
- lamination
- shear coordinates
- lambda length

- \def
- An ideal triangle in (S,M) is a triangle with vertices at M, whose sides are geodesics.
- \def
- A horocycle at marked point p is a set of points "equidistant" to p. In lift to H^2, looks like circle tangent to boundary at p.
Teichmuller space of a marked surface
Given marked surface (S,M) , the Teichmuller space T(S,M) is the space of metrics on (S,M) such that
- are hyperbolic (constant curvature -1)
- have geodesic boundary at boundary of S
- local neighborhood of point on boundary S can be mapped isometrically to neighborhood of a point here on one side of geodesic
- have cusps at points in M
Considered up to diffeomorphism homotopic to identity.
Facts
(1) T(S,M) contractible
(2) T(S,M) is manifold of dimension 6g-6+2p+3b+c where g = genus, p=# of puncture, b = # boundary component, c=# of marked points on boundary
