Singularity softening and avoidance by the action of thermal radiation in a generalized entropic cosmology

E. Elizalde, A. V. Yurov, A. V. Timoshkin

Some relevant aspects of a new form of generalized entropic cosmology, recently introduced by Nojiri, Odintsov and Faraoni, are considered. The setup is a logarithmic equation of s…

Secondary gravitational waves against a strong gravitational wave in the Bianchi VI universe

Konstantin E. Osetrin

A proper-time method for constructing models of dynamic gravitational-wave fields is presented. Using the proper-time method, analytical (not numerical) models of secondary gravita…

Linear perturbations of an exact gravitational wave in the Bianchi IV universe

Konstantin Osetrin

The proper-time method for constructing perturbative dynamical gravitational fields is presented. Using the proper-time method, a perturbative analytical model of gravitational wav…

Perfect fluid equations with N=1,2 Schrodinger supersymmetry

Timofei Snegirev

Superconformal extensions of the perfect fluid equations, which realize Schrodinger superalgebra, are constructed within the Hamiltonian formalism. They are built by introd…

Dirac stars with wormhole topology

Vladimir Dzhunushaliev, Vladimir Folomeev, Sayabek Sakhiyev

We consider configurations consisting of a gravitating nonlinear spinor field and a massless ghost scalar field providing a nontrivial spacetime topology. For such a mixed system,…

Two faces of superconformal mechanics

Sergey Krivonos, Armen Nersessian

Two variants of superconformal mechanics with manifest and -symmetries possessing exceptional dynamical symmetry are presented. To cons…
