Using the classical Lorentz-Hilbert-Einstein action, we derive the kinetic Vlasov-Maxwell-Einstein equation for particles in the gravitational and electromagnetic fields. The method of synchronization of intrinsic times of different particles is proposed. Based on the obtained expressions for actions (including in the post-Newtonian approximation), we analyze the connection of the cosmological lambda-term and dark energy.

The aim of the study is to identify the specific trends in the foreign population distribution throughout Switzerland from the middle of the XIX century until the present day, based on census data, statistical yearbooks, and the database of the Federal Statistical Office of Switzerland. As a result, we have found a high degree of inertia in the foreign population distribution on the territory of Switzerland and its simultaneous convergence with the citizen distribution in the country. The obtained results can be used to analyze the international population migration in other countries and in training courses on population geography and the socio-economic geography of foreign countries.
