Our approach leverages the fixed point principle to derive novel results concerning the existence and uniqueness of solutions to this system. Additionally, we establish further results by employing Schaefer's fixed point theorem, which allows us to extend the applicability of our findings. To illustrate the practical relevance and application of our theoretical results, we also provide a detailed example at the conclusion of the paper. At the end, an example is given.en10.22190/FUMI240319023Binfo:eu-repo/semantics/openAccessCaputo fractional derivativesHadamard fractional derivativesSchaefer's fixed point theoremArticle402319332WOS:001536337200004N/A
