This is an introduction course for undergraduate and graduate students who are interested on low-dimensional geometry and topology. Due to the uniformization theorem of surfaces and geometrization conjecture for 3-manifolds, we will use hyperbolic geometry as the basic tool. Hyperbolic metrics will be used to understand the Teichmuller space of surfaces and topology of 3-manifolds. The topics to be covered are:

1.      Hyperbolic spaces in dimension 2 and 3.

2.      Hyperbolic metrics on surfaces: geodesics, Gauss-Bonnet, collar lemmas, Ber’s constant, Wolpert’s cosine law.

3.      Teichmuller space of surfaces: Fenchel-Nielsen coordinate

4.      Mostow rigidity for hyperbolic metrics on 3-manifolds

       5.      Gromov norm and Gromov-Thurston’s theorem relating Gromov norm to volume






The students should know some basic algebraic topology (fundamental groups, covering spaces) and Riemannian geometry.
