一般Hamilton-Jacobi方程的弱KAM理论II:利普希茨条件下的基本解

Weak KAM theory for general Hamilton-Jacobi equations II: the fundamental solution under Lipschitz conditions

Lin Wang, Jun Yan

摘要:

本文考虑了具有初始条件的发展型Hamilton-Jacobi方程:\begin{equation*} \begin{cases} \partial_tu(x,t)+H(x,u(x,t),\partial_xu(x,t))=0,\\ u(x,0)=ϕ(x), \end{cases} \end{equation*}其中$ϕ(x)\in C(M,\mathbb{R})$ .在$H(x,u,p)$关于$p$的凸性和$H(x,u,p)$关于$u$的一致Lipschitz的假设下,建立了一个变分原理,并给出了粘性解与某些极小特征之间的内在联系.通过引入隐式定义的{ \it基本解},得到了发展Hamilton-Jacobi方程粘性解的变分表示公式.进一步讨论了发展型Hamilton-Jacobi方程粘性解的大时间行为,给出了$H(x,u,p)$关于$u$严格递增的定常Hamilton-Jacobi方程粘性解的动力学表示公式.

英文摘要:

We consider the following evolutionary Hamilton-Jacobi equation with initial condition: \begin{equation*} \begin{cases} \partial_tu(x,t)+H(x,u(x,t),\partial_xu(x,t))=0,\\ u(x,0)=ϕ(x), \end{cases} \end{equation*} where $ϕ(x)\in C(M,\mathbb{R})$. Under some assumptions on the convexity of $H(x,u,p)$ with respect to $p$ and the uniform Lipschitz of $H(x,u,p)$ with respect to $u$, we establish a variational principle and provide an intrinsic relation between viscosity solutions and certain minimal characteristics. By introducing an implicitly defined {\it fundamental solution}, we obtain a variational representation formula of the viscosity solution of the evolutionary Hamilton-Jacobi equation. Moreover, we discuss the large time behavior of the viscosity solution of the evolutionary Hamilton-Jacobi equation and provide a dynamical representation formula of the viscosity solution of the stationary Hamilton-Jacobi equation with strictly increasing $H(x,u,p)$ with respect to $u$.
