Zhang, Wei; Liu, Wenbin Existence, uniqueness, and multiplicity results on positive solutions for a class of Hadamard-type fractional boundary value problem on an infinite interval. (English) Zbl 1452.34017 Math. Methods Appl. Sci. 43, No. 5, 2251-2275 (2020). Summary: This paper focuses on a class of Hadamard-type fractional differential equation with nonlocal boundary conditions on an infinite interval. New existence, uniqueness, and multiplicity results of positive solutions are obtained by using Schauder’s fixed point theorem, Banach’s contraction mapping principle, the monotone iterative method, and the Avery-Peterson fixed point theorem. Examples are included to illustrate our main results.
