• An ideal triangle in (S,M) is a triangle with vertices at M, whose sides are geodesics.

• 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
