Abstract

In this article, we study spacelike and timelike rotational surfaces in a 3--dimensional de Sitter space S13\mathbb{S}^3_1 which are the orbit of a regular curve under the action of the orthogonal transformation of 4--dimensional Minkowski space E14\mathbb{E}^4_1 leaving a spacelike, a timelike or a degenerate plane pointwise fixed. We determine the profile curve of such Weingarten rotational surfaces parameterized by the principal curvature. Then, we classify spacelike and timelike Weingarten rotational surface in S13\mathbb{S}^3_1 with the principal curvatures κ\kappa and λ\lambda satisfying κ=aλ+b\kappa=a\lambda+b or κ=aλm\kappa=a\lambda^m for special cases of constants a,ba, b and mm.
