The existence and uniqueness theorem for isotropic hypersurfaces with prescribed boundary in Lorentzian warped products is proved. The proof is based on minimal Lipschitz extensions of functions.
Mots-clés : Lorentzian space
Keywords: isotropic surface, Lipschitz function, minimal extension of a Lipschitz function.
