By using some fixed point theorems including the Banach contraction mapping principle and SchaeferĄ¯s fixed point theorem, we obtain new existence and uniqueness results for our given problem. Also, we give some examples to illustrate our main results %U https://www.hindawi.com/journals/jam/2020/1212040/
