Abstract
In their remarkable paper, Fazli et al. (Int J Comput Math, 2019. 10.1080/00207160.2019.1658870) have recently established existence results for fractional Basset-Boussinesq-Oseen equation in an appropriate partially ordered Banach space. In this paper, we improve this study by proposing different approach that provides existence criterion for the addressed equation. The main assumptions are less restrictive and easily verifiable. Examples with graphical representations are constructed to demonstrate consistency to theoretical findings. Besides, we construct an iterative sequence that converges to the unique solution. We end the paper by a conclusion that demonstrates the advantage of our theorem compared to the previous results.
