各向异性回火扩散方程

Anisotropic tempered diffusion equations

Juan Calvo, Antonio Marigonda, Giandomenico Orlandi

摘要:

我们介绍了一个功能框架,它是特别适合制定几类各向异性发展方程的回火扩散型。在一组涉及非常自然的势函数的假设下,这些模型可以被证明属于由4,5设计的熵解框架,因此确保适定性。我们连接这个潜在的属性与相关的成本函数,从而提供了一个链接与最优输运理论和相对论费用函数的新的例子供应。此外,我们描述了这些模型的各向异性传播特性,我们确定的Rankine-Hugoniot条件,规则的时间演化的跳跃超曲面下的各向异性流。

英文摘要:

We introduce a functional framework which is specially suited to formulate several classes of anisotropic evolution equations of tempered diffusion type. Under an amenable set of hypothesis involving a very natural potential function, these models can be shown to belong to the entropy solution framework devised by 4, 5, therefore ensuring well-posedness. We connect the properties of this potential with those of the associated cost function, thus providing a link with optimal transport theory and a supply of new examples of relativistic cost functions. Moreover, we characterize the anisotropic spreading properties of these models and we determine the Rankine-Hugoniot conditions that rule the temporal evolution of jump hypersurfaces under the given anisotropic flows.
