Algebraic Formulation of the Operatorial Perturbation Theory. Part I
Ary W. Espinosa Müller, Adelio R. Matamala Vásquez
A new totally algebraic formalism based on general, abstract ladder operators has been proposed. This approach heavily grounds in the superoperator formalism of Primas. However it…

Static Einstein-Maxwell Solutions in 2+1 dimensions
Mauricio Cataldo, Patricio Salgado
We obtain the Einstein-Maxwell equations for (2+1)-dimensional static space-time, which are invariant under the transformation . It is…

Superposition of a static perfect fluid and a radial elecric field
Mauricio Cataldo, Patricio Salgado
We obtain a two-parameter set of solutions, which represents a spherically symmetric space-time with a superposition of a neutral fluid and an electric field. The electromagnetic f…
