Abstract
We study multidimensional control problems involving first-order partial differential equations. To ensure the existence of sufficiently regular multipliers (from the space \({C^{\ast}}\)) in the first-order necessary optimality conditions, some restrictions of the feasible domain have to be added. In particular, we investigate ‘class-qualified’ problems where the weak derivatives of \(x\) can be represented within a Baire function class. In the present paper, we prove conditions under which the original and the modified problems possess the same minimal values.
