Using the quantity z(bq,m) in terms of general relativity

Albert Einstein’s general theory of relativity describes gravitation through a deformation space-time. However, there is high degree parallelism between the linear approximation and Maxwell’s electromagnetism. The first laws allows one to derive Coulomb’s law and, therefore, correct radius dependency charge interaction. Both theories (general theory) are absolutely equivalent each other in derivation. Therefore, mass have analogous positions functions. This starting point for considering that it should be possible combine both into one. To do so, has formulated quantity z , which complex number combines charge. In this way, becomes electromagnetism theory.
