Conformal representations provide a way of describing a surface by holomorphic data. The origin of this representations was given by the Weierstrass-Enneper representation for minimal surfaces in ℝ3 which entailed a great development of the theory of this surfaces in the XIX century. In this work we study the Weierstrass-Enneper representation, the conformal representation of constant mean curvature one surfaces (Bryant surfaces) and null Gaussian curvature surfaces (at surfaces) in ℍ3 , and the interrelation between these three.Las representaciones conformes permiten describir una superficie por medio de datos holomorfos. El origen de estas representaciones tuvo lugar con la Representación de Weierstrass-Enneper para superficies mínimas en...
