摘要

The objective of this research is to establish specific adequate conditions aimed to guarantee the existence of weak solutions for various types of initial value problems, which involve variable order Hadamard fractional derivative. This is accomplished by employing Krasnoselskii’s type fixed point theorem and De Blasi measure of weak noncompactness. Furthermore, an illustrative example is presented to showcase our results.
