“…The Krasnosel'skiȋ-Guo Theorem, more in general, topological methods are a commonly used tool in the study of existence of positive solutions for the p-Laplacian equation (1.1) subject to different BCs. This is an active area of research, for example, homogeneous Dirichlet BCs have been studied in [1,5,16,25,31,37,43,47], homogeneous Robin BCs in [31,43,47], non local BCs of Dirichlet type in [3,4,6,7,9,14,24,39,41,48] and nonlocal BCs of Robin type in [14,30,32,40,42,48].…”
