We introduce Teichmuller space, an analytically tractable cover of Riemann’s moduli space of curves. We develop a coherent method of studying this space through Riemannian geometric methods. We hope to cover the basic definitions, the Weil-Petersson metric and curvature tensor (Royden, Tromba, Wolpert), the convexity of the length function (Wolpert), and the equivalence of the Thurston metric with the Weil-Petersson metric from a single perspective. If time allows, we may venture into the space of complex projective and convex real projective structures on a surface.



Some familiarity with complex analysis; the rudiments of Riemannian geometry including Riemannian metrics, curvature tensors and first & second variation formulas; the definition and some elementary properties of Riemann surfaces, including the rudiments of hyperbolic geometry.
