The Green function is constructed and the considered problem is reduced to the equivalent integral equation. The existence and uniqueness of the solutions for the given problem are analyzed by using the Banach contraction principle. The Schaeferâ€™s fixed point theorem is then<br />used to prove the existence of the solutions. Finally, the examples are given to verify the given theorems.</p>}, number={3}, journal={European Journal of Pure and Applied Mathematics}, author={Mardanov, Misir and Sharifov, Yagub and Ismayilova, Kamala and Zamanova, Sevinc}, year={2019}, month={Jul.}, pages={756–770} }
