Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Remarks on the vanishing viscosity process of state-constraint Hamilton-Jacobi equations
状态约束 哈密尔顿-雅可比方程 黏度消失
2023/4/21
We investigate the convergence rate in the vanishing viscosity process of the solutions to the subquadratic state-constraint Hamilton-Jacobi equations. We give two different proofs of the fact that, f...
