A two-grid algorithm based on expanded mixed element discretizations for strongly nonlinear elliptic equations
This paper deals with two-grid expanded mixed discretization techniques for the nonlinear Hamilton-Jacobi-Bellman problem with the source term \(f\) dependent on \(p\) and \(\nabla p\). It is proven that this formulation has a unique solution and is equivalent to the original partial differential problem. To illustrate the efficiency and accuracy of presented two-grid algorithm, the authors examine three numerical examples.
