In this paper, we investigate a class of nonlinear Langevin equation involving two fractional orders \(\alpha \in (0,1]\) and \(\gamma \in (1,2]\) with infinite-point boundary value conditions. By Leray–Schauder’s nonlinear alternative and Leray–Schauder degree theory, several new existence results of solutions are obtained. An example is given to show the applicability of our main results.
