José A. Carrillo, Tomasz Dębiec, Piotr Gwiazda, Agnieszka Świerczewska-Gwiazda

摘要:

我们考虑了几个无压变量的可压缩欧拉方程驱动的非局部repulsionattraction和对齐力与泊松相互作用。在能量容许准则下,我们证明了整体测度值解的存在性,即,非常弱解描述了一个经典的杨措施与适当的浓度缺陷。然后,我们调查的相对能量泛函的演变,比较的测量值的解决方案,正则解从相同的初始数据。这导致了(部分)弱-强唯一性原理。

英文摘要:

We consider several pressureless variants of the compressible Euler equation driven by nonlocal repulsionattraction and alignment forces with Poisson interaction. Under an energy admissibility criterion, we prove existence of global measure-valued solutions, i.e., very weak solutions described by a classical Young measure together with appropriate concentration defects. We then investigate the evolution of a relative energy functional to compare a measure-valued solution to a regular solution emanating from the same initial datum. This leads to a (partial) weak-strong uniqueness principle.
