Abstract:

We describe the space of isometric immersions from the Lorentz plane $\mathbb {L}^2$ into the anti-de Sitter $3$-space $\mathbb {H}_1^3$, and solve several open problems in this context raised by M. Dajczer and K. Nomizu in 1981. We also obtain from the above result a description of the space of Lorentzian flat tori isometrically immersed in $\mathbb {H}_1^3$ in terms of pairs of closed curves with wave-front singularities in the hyperbolic plane $\mathbb {H}^2$ satisfying some compatibility conditions.
