... The definition of Teichmüller space can be extended to general surfaces as the space of all metrics of constant curvature up to isotopy and change of scale. In the case of the torus T 2 , this space is the set of all Euclidean structures (i.e., metrics with constant curvature zero) on T 2 with area ...

... Definition 2.1. Let X be a topological space. A first category subset of X is a countable union of closed subsets with empty interior. A second category subset is a subset which is not a first category subset. Lemma 2.2 (Baire). In a complete metric space the complement of a first category subset is den ...

... situation is more subtle due to the torsion that may appear in the homology groups. We illustrate this on a few examples. In order to compute the homology of a surface, the first step could be to find a triangulation of this surface where triangles are “real”, i.e., two edges or two vertices of a tr ...
