Axially symmetric vacuum solutions of the bimetric relativity theory

On Kantowski–Sachs Cosmological Models in Bimetric Theory of Gravity

“…Cosmic strings are one-dimensional topological defects associated with spontaneous symmetry breaking whose plausible production site is cosmological phase transitions in the early universe (Kibble, 1976;Vilenkin, 1985). The present-day configurations of the universe are not contradicted by large-scale network of strings in the early universe.…”

“…Rosen (1973, 1975), Yilmaz (1975, Karade and Dhoble (1980), Karade (1980), and Israelit (1976, 1978, 1981 are some of the authors who have studied several aspects of bimetric theory of gravitation. In particular, Reddy and Venkateswarlu (1989), Reddy and Venkateswara Rao (1998), , and have established the non-existence of anisotropic spatially homogeneous Bianchi type cosmological models in bimetric theory when the source of gravitation is governed by either perfect fluid or mesonic perfect fluid.…”

On Plane Symmetric Domain Walls and Cosmic Strings in Bimetric Theory

“…A bar (|) stands for γ -covariant differentiation and T i j is the energy momentum tensor of matter fields. Rosen (1975), Yilmaz (1975), Karade and Dhoble (1980), Karade (1980), Reddy and Venkateswarlu (1989), Reddy and Rao (1998) Reddy (2003c). Mohanty et al (2002), Mohanty and Sahoo (2002a) have studied several aspects of bimetric theory of gravitation.…”
