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…
