In addition, we have established a set of definitions, concepts and some useful lemmas that are needed in our work.}, number={1}, journal={Al-Mustansiriyah Journal of Science}, author={Al-Saidy, Saheb K. and Maktoof, Hasan W. and Mazeel, Abdul Khaleq O. and Agaie, Baba Galadima}, year={2024}, month={Mar.}, pages={88–94} }
