In the paper, we study a boundary value problem for a class of ψ-Hilfer fractional-order Langevin equations with multi-point integral boundary conditions. Existence and uniqueness results are established by using well-known fixed point theorems. Examples illustrating the main results are also included.

ψ -Hilfer分数阶Langevin方程的非局部边值问题

在本文中，我们研究了一类具有多点积分边界条件的ψ-Hilfer分数阶Langevin方程的边值问题。存在性和唯一性结果是通过使用众所周知的不动点定理建立的。还包括说明主要结果的示例。
