“…Recently, a lot of attention has been paid to the study of problems involving the p-Laplacian operator and the p-biharmonic operator. We refer the reader to Alsaedi et al [1], Cung et al [10], Huang and Liu [15], and Sun and Wu [24,25]. The reason for studying these problems is their applications in fields such as quantum mechanics, flame propagation, and traveling waves in suspension bridges; for more applications see Bucur and Valdinoci [6], and Lazer and McKenna [16].…”
