We consider a self-consistent system of interacting spinor and scalar fields within the
framework of a Bianchi type-I (BI) cosmological model filled with perfect fluid. The interacting …

It is shown that the existence of static, cylindrically symmetric wormholes does not require
violation of the weak or null energy conditions near the throat, and cylindrically symmetric …

We study the evolution of a homogeneous, anisotropic Universe given by a Bianchi type-I
cosmological model filled with viscous fluid, in the presence of a cosmological constant Λ …

Within the scope of the Bianchi type VI models, the self-consistent system of nonlinear spinor
field and gravitational fields is considered. Exact self-consistent solutions to the spinor and …

The nature of cosmological solutions for a homogeneous, anisotropic Universe given by a
Bianchi type-I (BI) model in the presence of a cosmological constant Λ is investigated by …

We consider static and cylindrically symmetric interior string-type solutions in the scalar-
tensor representation of the hybrid metric-Palatini modified theory of gravity. As a first step in …

A system of minimally coupled nonlinear spinor and scalar fields within the scope of a
Bianchi type-I (BI) cosmological model in the presence of a perfect fluid and a cosmological …

We consider the problem of the existence of soliton-like self-gravitating cylindrically
symmetric configurations of a classical spinor field with the nonlinearity F (S)(S= ̄ ψ ψ, F is …

We discuss static, cylindrically symmetric vacuum solutions of hybrid metric-Palatini gravity
(HMPG), a recently proposed theory that has been shown to successfully pass the local …

The general stationary cylindrically symmetric solution of Einstein-massless scalar field
system with a nonpositive cosmological constant is presented. It is shown that the general …
