A Kamenev-type oscillation result for a linear [formula omitted]-order fractional differential equation.

We investigate the eventual sign changing for the solutions of the linear equation x ( α ) ′ + q ( t ) x = 0 , t ⩾ 0 , when the functional coefficient q satisfies the Kamenev-type restriction lim sup t → + ∞ 1 t ε ∫ t 0 t ( t - s ) ε q ( s ) ds = + ∞ for some ε > 2 , t 0 > 0 . The operator x ( α ) is the Caputo differential operator and α ∈ ( 0 , 1 ) . [ABSTRACT FROM AUTHOR]
