    Differential form approach for stationary axisymmetrical Maxwell fields in general-relativity
    (IOP Publishing Ltd, 1994-06) Fenández Jambrina, L.; Chinea Trujillo, Francisco Javier
    A formulation for stationary axisymmetric electromagnetic fields in general relativity is derived by casting them into the form of an anisotropic fluid. Several simplifications of the formalism are carried out in order to analyse different features of the fields, such as the derivation of electromagnetic sources for the Maxwell field in the form of thin layers, construction of new solutions, and generation techniques.

    Angular momentum surface density of the kerr metric
    (American Physical Society, 1993-10-18) Fernández Jambrina, L.; Chinea Trujillo, Francisco Javier
    A method for interpreting discontinuities of the twist potential of vacuum stationary axisymmetric solutions of Einstein's equations is introduced. Surface densities for the angular momentum of the source can be constructed after solving a linear partial differential equation with boundary conditions at infinity. This formalism is applied to the Kerr metric, obtaining a regularized version of the density calculated with other formalisms. The main result is that the integral defining the total angular momentum is finite for the Kerr metric.

    New first integral for twisting type-N vacuum gravitation fields with two non-commuting Killing vectors
    (IOP Publishing Ltd, 1998-02) Chinea Trujillo, Francisco Javier
    A new first integral for the equations corresponding to twisting type-N vacuum gravitational fields with two non-commuting Kilting vectors is introduced. A new reduction of the problem to a complex second-order ordinary differential equation is given. Alternatively, the mentioned first integral can be used in order to provide a first integral of the second-order complex equation introduced in a previous treatment of the problem.

    Singularity-free space-time
    (Amer Physical Soc, 1992-01-15) Chinea Trujillo, Francisco Javier; Fernández Jambrina, Leonardo; Senovilla, J. M. M.
    We show that the solution published in the paper by Senovilla [Phys. Rev. Lett. 64, 2219 (1990)] is geodesically complete and singularity-free. We also prove that the solution satisfies the stronger energy and causality conditions, such as global hyperbolicity, the strong energy condition, causal symmetry, and causal stability. A detailed discussion about which assumptions in the singularity theorems are not satisfied is performed, and we show explicitly that the solution is in accordance with those theorems. A brief discussion of the results is given.
