The target of this paper is to handle a nonlocal boundary-value problem for a specific kind of nonlinear fractional differential equations encapsuling a collective fractional derivative known as the $\psi$-Caputo fractional operator. The applied fractional operator generated by the kernel is of the following kind: $k(t,s)=\psi (t)-\psi(s).$  The existence of the solutions of the above-mentioned equations is tackled by using Mönch's fixed-point theorem combined with the technique of measures of noncompactness. In addition, we discuss the problem of stability within the scope of the Ulam–Hyers stability criteria for the main fractional system.  Finally, an example is given to illustrate the viability of the reported results. |
