SILVA-ORTIGOZA, G.  e  GARCIA-GODINEZ, P.. Familias de superficies nulas en el espacio-tiempo tridimensional de Minkowski y sus ecuaciones diferenciales asociadas. Rev. mex. fis. [online]. 2004, vol.50, n.1, pp.70-83. ISSN 0035-001X.

In this work we describe the procedure to obtain all the family of third order ordinary differential equations connected by a contact transformation such that in their spaces of solutions is defined a conformal three demensional Minkowski metric.

Palavras-chave : Minkowski space-time; null surfaces; third order ordinary differential equations.
