• Bianchi Type-I cosmological mesonic stiff fluid models in Lyra's geometry

Bianchi Type-I cosmological models in Lyra's geometry are obtained when the source of gravitational field is a perfect fluid coupled with massless mesonic scalar field. Some physical and kinematical properties of the models are also discussed.

• Einstein–Rosen inflationary Universe in general relativity

Einstein–Rosen inflationary Universe is investigated in the presence of mass-less scalar field with a flat potential. To get an inflationary Universe, we have considered a flat region in which the potential V is constant. Some physical properties of the model are discussed.

• Bianchi type-I massive string magnetized barotropic perfect ﬂuid cosmological model in bimetric theory

Bianchi type-I massive string cosmological model for perfect ﬂuid distribution in the presence of magnetic ﬁeld is investigated in Rosen’s [Gen. Relativ. Gravit. 4, 435 (1973)] bimetric theory of gravitation. To obtain the deterministic model in terms of cosmic time, we have used the condition $A = (B C)^n$, where n is a constant, between the metric potentials. The magnetic ﬁeld is due to the electric current produced along the 𝑥-axis with inﬁnite electrical conductivity. Some physical and geometrical properties of the exhibited model are discussed and studied.

• A higher-dimensional Bianchi type-I inﬂationary Universe in general relativity

A ﬁve-dimensional Bianchi type-I inﬂationary Universe is investigated in the presence of massless scalar ﬁeld with a ﬂat potential. To get an inﬂationary Universe, a ﬂat region in which the potential $V$ is constant is considered. Some physical and kinematical properties of the Universe are also discussed.

• Quark matter coupled to domain walls in Bianchi types II, VIII and IX Universes

In this study of Bianchi types II, VIII and IX Universes, quark matter coupled to domain walls in the context of general relativity are explored. To obtain deterministic solution of the Einstein’s field equations, various techniques are adopted. The features of the obtained solution are discussed.
