DESCRIPTION:Speakers: Julia Tchemarina (Tver State University)\nMathematic
al modeling of gravitating configurations of physical fields is one of the
priority directions of the modern theory of gravity. Most of the exact so
lutions constructed within the framework of the general relativity are sta
tic or stationary configurations. This is due to the objective complexity
of solving the Einstein equations under the assumption of nonstationarity.
We present an approach to constructing nonstationary configurations of a
spherically symmetric nonlinear real scalar field and the electromagnetic
field\, which are assumed both to be minimally coupled to gravity. It is b
ased on the separation of one invariant equation\, written in terms of the
characteristic function and scalar field potential. Using the proposed me
thod\, an exact nonstationary solution with a nontrivial topology of space
-time will be constructed.\n\nhttps://indico.particle.mephi.ru/event/22/co
