The kinetic one-dimensional equation with frequency of collisions, affine depending on the module molecular velocity

The one-dimensional kinetic equation with integral of collisions type BGK (Bhatnagar, Gross and Krook) and frequency of collisions affine depending on the module of molecular velocity is constructed. Laws of preservation of number of particles, momentum and energy at construction equation are used. Separation of variables leads to the characteristic equation. The system of the dispersion equations is entered. Its determinant is called as dispersion function. It is investigated continuous and discrete spectra of the characteristic equation. The set of zero of the dispersion equation makes the discrete spectrum of the characteristic equation. The eigen solutions of the kinetic equation corresponding to discrete spectrum are found. The solution of the characteristic equation in space of the generalized functions leads to eigen functions corresponding to the continuous spectrum. Results of the spent analysis in the form of the theorem about structure of the general solution of the entered kinetic equation are formulated.
