| Abstract: | It is shown that a periodic two-dimensional isentropic motion of a gas exists and it is described by an exact solution of
the equations of gas dynamics. A polytropic gas that fills a circular cylinder rotates and oscillates (in the radial direction)
simultaneously under the action of periodically changing external pressure. The solution obtained belongs to the class of
solutions with a velocity field that is linear in the coordinates (with homogeneous deformation).
