Most of the existing results in the literature assume the continuity of theinvolved kernel. We consider here a kernel that is not necessarily continuous, namely, the kernel of the RiemannLiouville fractional integral operator that might be singular. We determine certain sufficient conditions underwhich the solutions, in an appropriate underlying space, behave eventually like power functions. For this purpose,we establish and generalize some well-known integral inequalities with some crucial estimates. Our findings aresupported by examples and numerical calculations.83120208312020341348https://www.wseas.org/multimedia/journals/control/2020/a705103-043.pdf10.37394/23203.2020.15.35https://www.wseas.org/multimedia/journals/control/2020/a705103-043.pdf10.1007/s10440-008-9356-6R.
