Relativistic Electromagnetic Mass Models With Cosmological Variable$Λ$ in Spherically Symmetric Anisotropic Source

A class of exact solutions for the Einstein-Maxwell field equations are obtained by assuming the erstwhile cosmological constant $Λ$ to be a space-variable scalar, viz., $Λ=Λ(r)$. The source considered here is static, spherically symmetric and anisotropic charged fluid. The solutions obtained are matched continuously to the exterior Reissner-Nordström solution and each of the four solutions represents an electromagnetic mass model.
