一类带约束的Hamilton-Jacobi方程的唯一性

Uniqueness in a class of Hamilton-Jacobi equations with constraints

Sepideh Mirrahimi, Jean-Michel Roquejoffre

摘要:

本文讨论了一类依赖于时间函数的含时Hamilton-Jacobi方程,该函数的选择是为了使解的最大值保持为常值0.注记的主要结果是:全问题有唯一的经典解。动机是一个选择突变模型,在小扩散的限制下,表现出浓度的Hamilton-Jacobi方程的解的零水平集。我们证明的唯一性结果意味着强收敛和误差估计的选择-变异模型。

英文摘要:

In this note, we discuss a class of time-dependent Hamilton-Jacobi equations depending on a function of time, this function being chosen in order to keep the maximum of the solution to the constant value 0. The main result of the note is that the full problem has a unique classical solution. The motivation is a selection-mutation model which, in the limit of small diffusion, exhibits concentration on the zero level set of the solution of the Hamilton-Jacobi equation. The uniqueness result that we prove implies strong convergence and error estimates for the selection-mutation model.
