We consider the singular Riemann problem for the rectilinear isentropic compressible Euler equations with discontinuous flux,more specifically,for pressureless flow on the left and polytropic flow on the right separated by a discontinuity x=x(t).We prove that this problem admits global Radon measure solutions for all kinds of initial *** over-compressing condition on the discontinuity x=x(t)is not enough to ensure the uniqueness of the ***,there is a unique piecewise smooth solution if one proposes a slip condition on the right-side of the curve x=x(t)+0,in addition to the full adhesion condition on its *** an application,we study a free piston problem with the piston in a tube surrounded initially by uniform pressureless flow and a polytropic *** particular,we obtain the existence of a piecewise smooth solution for the motion of the piston between a vacuum and a polytropic *** indicates that the singular Riemann problem looks like a control problem in the sense that one could adjust the condition on the discontinuity of the flux to obtain the desired flow field.
