摘要：In this talk, we will report the life span of the axisymmetric non-vacuum solutions without swirl for the compressible Euler equations. By applying the vortex equation for the axisymmetric flow without swirl, we prove that there exist the corresponding blowup results for the C2 solutions with a sufficiently large initial functional.
