Dependence of the Gauss-Codazzi equations and the Ricci equation of Lorentz surfaces [PDF]

open access: yes, 2013
The fundamental equations of Gauss, Codazzi and Ricci provide the conditions for local isometric embeddability. In general, the three fundamental equations are independent for surfaces in Riemannian 4-manifolds. In contrast, we prove in this article that
