Elisabetta Chiodaroli, Eduard Feireisl, Ondrej Kreml

摘要:

本文考虑描述可压缩热传导气体运动的Euler-Fourier方程组的弱解。利用凸积分的方法,我们证明了对于任意光滑初值,该问题存在无穷多个时间上全局弱解。我们还表明,对于任何初始分布的密度和温度,存在一个初始速度,使相关的初值问题具有无穷多个解决方案,保持总能量。

英文摘要:

We consider the weak solutions to the Euler-Fourier system describing the motion of a compressible heat conducting gas. Employing the method of convex integration, we show that the problem admits infinitely many global-in-time weak solutions for any choice of smooth initial data. We also show that for any initial distribution of the density and temperature, there exists an initial velocity such that the associated initial-value problem possesses infinitely many solutions that conserve the total energy.
