“…In 2016, Gautam and Dabas [32] established mild solutions for a class of neutral fractional functional differential equations with NII. Nowadays, most researchers [18,21,24,30,[33][34][35][36] study non-instantaneous impulses with the HFD. Researchers delve into the study of non-densely defined operators to tackle the complexities of control and ensure the efficient operation of a wide range of systems, from robotics and autonomous vehicles to power grids and biological networks [9,10,14,19,22,25].…”
