A class of iterative functional fractional differential equation on infinite interval.

In this paper, a class of iterative functional fractional differential equations on the infinite interval with integral boundary conditions are presented. The existence theorem of positive solutions are established by using monotone iterative technique. The results obtained in this paper reflect the influence of feedback iteration term on the existence of solutions. Finally, an example is given out to illustrate the adaptability and universality of our main results.(c) 2022 Elsevier Ltd. All rights reserved.
