Fixed points of mapping of N-point gravitational lenses
Albert Kotvytskiy, Volodymir Shablenko, Evgenij Bronza
In this paper, we study fixed points of N-point gravitational lenses. We use complex form of lens mapping to study fixed points. Complex form has an advantage over coordinate one b…
Estimating the number of solutions equation of N-point gravitational lens algebraic geometry methods
Albert Kotvytskiy, Semen Bronza, Svatoslav Vovk
One of the main problems in the study of system of equations of the gravitational lens, is the computation of coordinates from the known position of the source. In the process of c…
Three Einstein rings: explicit solution and numerical simulation
Elena Yu. Bannikova, Albert T. Kotvytskiy
We investigated the effects of gravitational lensing for a system in which a lens is a point mass and a homogeneous disc with a central hole. In such system there is a variety of c…
Generalized interaction in multigravity
Steven Duplij, Albert Kotvytskiy
A general approach to description of multigravity models in D-dimensional space-time is presented. Different possibilities of generalization of the invariant volume are given. Then…
Non-linear constitutive equations for gravitoelectromagnetism
Steven Duplij, Elisabetta Di Grezia, Giampiero Esposito +1
This paper studies non-linear constitutive equations for gravitoelectromagnetism. Eventually, the problem is solved of finding, for a given particular solution of the gravity-Maxwe…
