A geometrical correspondence between maximal surfaces in anti-De Sitter   space-time and minimal surfaces in $\mathbb{H}^2\times \mathbb{R}$
  A geometrical correspondence between maximal surfaces in anti-De Sitter space-time and minimal surfaces in the Riemannian product of the hyperbolic plane and the real line is established. New examples of maximal surfaces in anti-De Sitter space-time are obtained in order to illustrate this correspondence.
