From Geometry to Physics -- AZ: touches to the portrait
Yurii Ignat'ev
The process launched by Lobachevsky. The movement of the Kazan school of geometry towards physics. Personal memories of Alexei Zinovievich Petrov, the great Kazan geometer and theo…
Self-gravitating Higgs field of scalar charge. II. Asymmetric scalar doublet
Yu. G. Ignat'ev
The self-gravitating Higgs field of a scalar charge is studied for the case of an asymmetric scalar doublet containing, along with a canonical and a phantom component. It is shown…
Evolution of spherical perturbations in the cosmological environment of the Higgs scalar field and an ideal scalar charged fluid
Yu. G. Ignat'ev
A mathematical model of the evolution of spherical perturbations in a cosmological ideal scalar-charged fluid with scalar Higgs interaction is constructed. A closed mathematical mo…
Evolution of plane perturbations in the cosmological environment of the Higgs scalar field and an ideal scalar charged fluid
Yu. G. Ignat'ev
A phenomenological model of an ideal fluid with a scalar charge is formulated, on the basis of which a model with a neutral fluid and a vacuum-field model with rules of transition…
Cosmological models based on an asymmetric scalar doublet with kinetic coupling of components. II. Numerical modeling
Yu. G. Ignsat'ev, I. A. Kokh
Numerical modeling of a mathematical model of the cosmological evolution of an asymmetric scalar doublet with kinetic interaction between the components was carried out. A wide ran…
