A method of researches - theoretical, based on the functional analysis. The analytical solution of models of the task about own oscillations of fluid in the flat channel is obtained. The problems of convergence of a projective method Galerkin are investigated at problem solving on eigenvalues. The theorems establishing connection between eigenvalues and the eigenvectors of the exact and approximating tasks are proved. The example of a numerical realization of approximate driving of fluid is given, in particular, at the substantation of use of the numerical methods in the linear theory of a hydrodynamic stability Product Description popup.authors popup.nrat_date 2020-04-02 Close
