Abstract

We generalize in Lorentz–Minkowski space ${\mathbb{𝕃}}^{3}$ the two-dimensional analogue of the catenary of Euclidean space. We solve the Dirichlet problem when the bounded domain is mean convex and the boundary data has a spacelike extension to the domain. We also classify all singular maximal surfaces of ${\mathbb{𝕃}}^{3}$ invariant by a uniparametric group of translations and rotations.
