Oscillation of differential equations in the frame of nonlocal fractional derivatives generated by conformable derivatives

Recently, Jarad et al. in (Adv. Differ. Equ. 2017:247, 2017) defined a new class of nonlocal generalized fractional derivatives, called conformable fractional derivatives (CFDs), based on conformable derivatives. In this paper, sufficient conditions are established for the oscillation of solutions of generalized fractional differential equations of the form $$ \textstyle\begin{cases}...
