Аннотация:A hydrodynamic model of a highly flattened galaxy is obtained which corresponds to real galaxies much better than a cylindrical or disk model. The model is developed by solving a one-dimensional problem of stellar-system dynamics in quadratures. A method is proposed for taking into account the finite thickness of the system when considering wave processes in galaxies described by such a model.
