Relativistic Electromagnetic Mass Models With Cosmological Variable in Spherically Symmetric Anisotropic Source
R. N. Tiwari, Saibal Ray, Sumana Bhadra
A class of exact solutions for the Einstein-Maxwell field equations are obtained by assuming the erstwhile cosmological constant to be a space-variable scalar, viz., $ Λ=Λ(r)…
