A sequence of necessary actions for the formulation of free leptonic equations (Dirac algorithm) is established. A complete and closed set of equations for the description of massive and massless, charged and neutral, stable and unstable leptons is o

Static and dynamic properties of a two-sublattice non-Heisenberg magnet with complex interion anisotropy of both bilinear and biquadratic exchange interactions are investigated. Existence conditions are found for phases with the dipole order paramete

The Ising model with the frustrated exchange interaction for strongly anisotropic antiferromagnetic ultrathin film is investigated in the mean field approximation at low temperatures. It is shown that a spatially inhomogeneous state can be accomplish

A phase diagram of a magnetic material with the spin S = 2 is obtained including all allowed spin invariants for the isotropic exchange interaction at an arbitrary relation between exchange constants. New phases with two-sublattice structure and biax

The influence of the anisotropic exchange interaction on the phase states of a non-Heisenberg ferromagnet with a magnetic-ion spin S = 1 is studied. It is shown that, depending on the relationships between the parameters of anisotropic exchange inter

We study the effect of interionic anisotropy on the phase states of a non-Heisenberg ferromagnet with magnetic ion spin S = 1. It is shown that depending on the relation between the interionic anisotropy constants, uniaxial and angular ferromagnetic

In the mean-field approximation, static and dynamic properties of isotropic ferrimagnet with two sub-lattices with spin equaling one and spin one-half are investigated. It was shown that the account of non-Heisenberg (biquadratic) exchange interactio

A study of two-dimensional topological vortex-like solitons, for spin nematic states in magnets with spin S = 1 and S = 3/2. Depending on the parameters of the magnet, we get either pure multipole vortices, with a quadrupole parameter for S = 1, or a
