摘要
A family of self-similar and global bounded weak solutions are constructed rigorously for all positive time to the two-dimensional pressure-gradient system in this paper. By using the axisymmetric and self-similar assumptions, the equations are reduced to a system of ordinary differential equations, from which we obtain detailed structures of solutions as well as their existence. On this basis, we explore the behavior of characteristics near the sonic boundary.
