Abstract
Based upon the view that the interstellar medium composed of a hot gas, a warm gas, and cold clouds is regulated by supernova remnants, its time variation is studied by use of model equations. Similar to nonlinear oscillators, three types of solutions are found. They are a stable stationary state (focus), a limit cycle, and a runaway state. It is suggested that each solution corresponds to a realistic state of interstellar medium. An entrained state of interstellar medium by an external periodic force shows a chaotic state and/or a new limit-cycle state, depending upon the frequency and the amplitude of the external force. The present result suggests a new approach to the evolution of galaxies.
