Generalized Metrical Multi-Time Lagrange Model for General Relativity   and Electromagnetism
  The paper construct a suitable generalized metrical multi-time Lagrange geometrical model for both gravitational and electromagnetic fields, in a general setting. In this construction, the gravitational potentials are described by a distinguished vertical metrical tensor of the form $h^{/alpha/beta}e^{2\sigma}/phi_{ij}$.
