Camassa-Holm及相关模型中利用非唯一特征的能量转移

Transfer of energy in Camassa-Holm and related models by use of nonunique characteristics

Grzegorz Jamróz

摘要:

研究了Camassa-Holm方程及相关方程的有限能量弱解中能量密度的传播.发展的方法的基础上,广义非唯一的特征,我们表明,部分的能量有关的正,负斜率是单侧弱连续和有界变化,这使我们能够定义一定的措施,这两个部分的能量耗散。结果是一个开放的问题的唯一性耗散的Camassa-Holm方程的一步。

英文摘要:

We study the propagation of energy density in finite-energy weak solutions of the Camassa-Holm and related equations. Developing the methods based on generalized nonunique characteristics, we show that the parts of energy related to positive and negative slopes are one-sided weakly continuous and of bounded variation, which allows us to define certain measures of dissipation of both parts of energy. The result is a step towards the open problem of uniqueness of dissipative solutions of the Camassa-Holm equation.
