报告地点：Zoom会议 ID: 995 2883 7300
报告简介：In this talk, the non-isentropic and incompressible Euler equations are the classical modeling in fluid dynamics. Considering a fluid filling a bounded domain in (), by vacuum for, we combine the functional of the average radial moment, with an estimate of the moment inertia proposed by Sideris; and with the integration method to make an advancement in the solutions to the problem of obtaining blowup results for the case of solution to the Euler equations. To the best of our knowledge, for the compressible Euler equations, Lei-Du-Zhang obtained the first blowup result for for the Cauchy problem with solutions and vacuum with the radial symmetry assumption. We obtain the first blowup result for for the Cauchy problem with solutions and vacuum and without the radial symmetry assumption.
