Сценарий пересоединения в короне солнца с простой дискретизацией
In this paper, one of the possible scenarios for the creation of heteroclinic separators in the solar corona is described and realized. This reconnection scenario connects the magnetic field with two zero points of different signs, the fan surfaces of which do not intersect, with a magnetic field with two zero points which are connected by two heteroclinic separators. The method of proof is to create a model of the magnetic field produced by the plasma in the solar corona and to study it using the methods of the theory of dynamical systems. Namely, in the space of vector elds on the sphere S3 with two sources, two sinks and two saddles, we construct a simple arc with two saddle-node bifurcation points that connects the system without heteroclinic curves to a system with two heteroclinic curves. Discretization of this arc is also a simple arc in the space of diffeomorphisms. The results are new.
