►Removing the singularities of this curve gives rise to a two-dimensional connected manifold with a complex-analytic structure, that is, a Riemann
surface. All compact Riemann surfaces can be obtained this
way.
►Since a Riemann surface is a two-dimensional manifold that is orientable (owing to its analytic structure), its only topological invariant is its genus
(the number of handles in the surface).

►If a local coordinate is chosen on the Riemann surface, then the local coordinate representation of these holomorphic differentials is given by
