Steady and self similar full Euler flow

Original · EN

We consider solutions to the full (non-isentropic) two-dimensional Euler equations that are constant in time and along rays emanating from the origin. We prove that for a polytropic equation of state, entropy admissible solutions in L∞ with non-vanishing velocity, density, and internal energy must be BV. Moreover, we obtain some results concerning the structure of such solutions.
