Abstract

The analytical properties of solutions of the nonlinear differential equations x(α)(t)=f(t,x), α, 0<α1 of noninteger order have been investigated. We obtained two results concerning the frame curves of solutions. Moreover, we proved a result on differential inequality with fractional derivatives.
