Under suitable assumptions and with given quaternary continuous classical boundary control vector (QCCBCV), the existence theorem for a unique quaternary state vector solution (QSVS) of the weak form (WF) for the QNLPBVP is stated and demonstrated via the Method of Galerkin and the first compactness theorem. Furthermore, the continuity of the Lipchitz operator between the QSVS of the WF for the QLPBVP and the corresponding QCCBCV is proved. The existence of a quaternary continuous classical boundary optimal control vector (QCCBOVC) is stated and demonstrated under suitable assumptions.</p>}, number={3}, journal={Al-Mustansiriyah Journal of Science}, author={Naji, Fetan J. and Al-hawasy, Jamil Amir and Chryssoveghi, Ion}, year={2023}, month={Sep.}, pages={86–101} }
