  1. A factorization approach for solving the Hamilton-Jacobi equations in nonlinear optimal control

    … elementary solutions are then presented. The second approach involves converting the first-order HJ partial differential equation (PDE) to a second-order PDE. Then using a suitable parameterization, this second-order PDE is converted to a coupled system of higher-order nonlinear PDEs which can …

  2. Similarity Solutions for the Two-Dimensional Diffusion–Advection Equation in Sharp-Corner Geometries

    … reducing the equation to a time-independent second-order PDE. By modifying the ansatz, the problem can be recast as an eigenvalue problem. Exploiting elliptic regularity and the strong maximum principle, we invoke the Krein-Rutman theorem to establish the existence and domain-size …
