Abstract:
We find exact solutions to Einstein-Maxwell field equations which can be used to
model the interior of charged relativistic anisotropic fluid sphere. The field equations are transformed
to a simpler form using the transformation; the integration of the system is reduced to solving the
condition of pressure anisotropy. The solution of the system is reduced to a difference equation with
variable rational coefficients which can be solved in general. It is possible to obtain general class of
solutions in terms of special functions and elementary functions for different model parameters. Our results contain particular models found previously including models of charged relativistic anisotropic
spheres.
