83) t0 Using the identity |y1 − y2 |2 = |y1 − y3 |2 + 2 y1 − y3 , y3 − y2 + |y3 − y2 |2 , (84) the scalar products can be expanded into the sum of the squares: |x1n+1 − x1∗ |2 + |x1n+1 − x1n |2 + |p1n+1 − p1∗ |2 + |p1n+1 − p1n |2 + t1 t1 |x n+1 (t) − x ∗ (t)|2 dt + t0 + t1 t1 |un+1 (t) − u∗ (t)|2 dt + t0 + |un+1 (t) − un (t)|2 dt t0 t1 t1 |ψ n+1 (t) − ψ ∗ (t)|2 dt + t0 + |x n+1 (t) − x n (t)|2 dt t0 t0 t1 |x n (t) − x ∗ (t)|2 dt + t0 t1 |ψ n+1 (t) − ψ n (t)|2 dt ≤ |x1n − x1∗ |2 + |p1n − p1∗ |2 |un (t) − u∗ (t)|2 dt + t0 t1 |ψ n (t) − ψ ∗ (t)|2 dt.

Finally, the theorem is proved. Thus, the global numerical process (57)–(59) takes place simultaneously in the functional and finite-dimensional spaces. The control functions, state and adjoint trajectories are moving in functional spaces, while a free right-hand end point of the state trajectory is being iteratively transformed in finite-dimensional space. The process has a weak limit point which is the solution of the original system. The primal and dual functional components of this limit point form a saddlepoint of the augmented Lagrangian (48), its primal and dual vector components produce a saddlepoint of finite-dimensional augmented Lagrangian (96).
