具有密度依赖阻尼的Euler-Poisson方程组解的奇异性抑制

Suppression of singularities of solutions of the Euler-Poisson system with density-dependent damping

Olga S. Rozanova

摘要:

我们找到了一维排斥Euler-Poisson系统阻尼系数依赖于密度的一个尖锐条件,这使得在任意光滑数据的Cauchy问题的解中抑制奇异性的形成成为可能.在等离子体物理学的背景下,这意味着抑制冷等离子体的任意振荡的击穿的可能性。

英文摘要:

We find a sharp condition on the density-dependent coefficient of damping of a one-dimensional repulsive Euler-Poisson system, which makes it possible to suppress the formation of singularities in the solution of the Cauchy problem with arbitrary smooth data. In the context of plasma physics, this means the possibility of suppressing the breakdown of arbitrary oscillations of cold plasma.
