The uniqueness results for the given problem are obtained by applying Banach\u2019s contraction mapping principle and the Boyd\u2013Wong fixed point theorem for nonlinear contractions. Based on the Laray\u2013Schauder alternative and the well-known fixed-point theorem due to Krasnosel\u2019ski\u012d, the existence of solutions for the problem at hand is established under different criteria.
