Boundary Control Problem for a Nonlinear Convection–Diffusion–Reaction Equation
- 3 Downloads
The solvability of boundary-value and extremum problems for a nonlinear convection–diffusion–reaction equation with mixed boundary conditions is proved in the case where the coefficient in the boundary condition is a fairly arbitrary function of the solution to the boundary value problem. For the mass transfer coefficient equal to the modulus of the substance concentration, local stability estimates of the solution to the extremum problem with respect to relatively small perturbations in the cost functional and the given functions of the boundary value problem are obtained.
