报告简介：
This talk considers the general N-dimensional isothermal compressible Euler equations such that the initial density has a positive background density. By investigating the relations between the total reference mass, total reference energy, and the reference second inertia H(t) in the case with background density, we establish a finite time blowup result with large data. It is shown that sufficiently large values of -(H(0) + H'(0)) guarantee that the classical solutions of the system cannot survive smoothly on or before the time t = 1. This is described as a sole blowup condition depending only on the initial data and initial parameters.
