Least action principle for gravity and electrodynamics, the Lambda-term and the analog of Milne–McCrea solution for Lorentzian metric

We consider the derivation from the least action principle of relativistic and weakly relativistic Vlasov–Einstein equations. We also use the Vlasov–Einstein equations to analyze the dynamics and the evolution of certain structures. This approach enables to describe broad class of systems and their...

Zusammenfassung:We consider the derivation from the least action principle of relativistic and weakly relativistic Vlasov–Einstein equations. We also use the Vlasov–Einstein equations to analyze the dynamics and the evolution of certain structures. This approach enables to describe broad class of systems and their evolution, including the accelerated expansion of the universe with the cosmological constant and the recently arisen tensions.
