“…The main results on exact penalty functions for various variational problems from other works [13][14][15][16][17][18][19] are based on the assumptions that the objective function is Lipschitz continuous on a rather complicated and possibly unbounded set, and a penalty function attains a global minimum in the space of piecewise continuous functions for any sufficiently large value of the penalty parameter, and it is, once again, unclear how to verify these assumptions in any particular case. The same remark is true for the main results of the papers [9][10][11][12]20,21 devoted to exact penalty functions for optimal control problems. To the best of authors' knowledge, the only verifiable sufficient conditions for the global exactness of an exact penalty function in the infinite dimensional setting were obtained in the work of Gugat and Zuazua, 26 where the exact penalisation of the terminal constraint for optimal control problems involving linear evolution equations was considered.…”

“…From the second inequality in (9) and the fact that is bounded below, it obviously follows that, for any ≥ 0, the penalty function Φ is bounded below on A, and the set S (c) is bounded in L d s (0, T) × L m q (0, T). By applying (11) and the first inequality in (9), one obtains that, for any (…”

“…Recall that one says that the Mangasarian-Fromovitz constraint qualifications (MFCQ) holds at a point x T ∈ R d , if the gradients ∇g k (x T ), k ∈ J, are linearly independent, and there exists h ∈ R d such that ⟨∇g k (x T ), h⟩ = 0 for any k ∈ J, and ⟨∇g i (x T ), h⟩ < 0 for any i ∈ I(x T ). Let us show that the complete controllability of the linearized system along with MFCQ guarantee the local exactness of the penalty function Φ for problem (39) Theorem 12. Let U = L m q (0, T), q ≥ p, and (x*, u*) be a locally optimal solution of problem (39).…”

Let U = L m q (0, T), q ≥ p, and (x*, u*) be a locally optimal solution of problem (39). Suppose also that Assumptions 1, 2, and 3 of Theorem 11 are satisfied, is locally Lipschitz continuous, the functions g i , i ∈ I ∪ J are continuously differentiable in a neighbourhood of x*(T), and MFCQ holds true at the point x*(T).…”
