By leveraging these inequalities, we can establish important results related to disconjugacy for the fractional differential equations. The inequalities we propose not only generalize but also enrich existing research in the literature, effectively addressing exceptional cases of fractional differential equationsendisconjugacyForced sublinearForced superlinearGeneralized Caputo derivatives (Katugampola derivative)Article
