Abstract

In this article, we consider higher order fractional nonlinear differential equation of type \begin{align*} &_aD_t^qx(t)-p(t)x(t)+\sum_{i=1}^m q_i(t)|x(t)|^{\lambda_i-1}x(t)=v(t)\notag\\ &\underset{t\rightarrow a^+}{\lim}J_a^{n-q}x(t)=a_n\\ &_aD_t^{q-k}x(a)=a_k, \quad\quad\ k=1,...,n-1\notag \end{align*} where $_aD_t^q$is Riemann-Liouville fractional differential operator of order $q$, $m-1<q\leq m, m\geq1$ is an integer. We obtain some oscillation criteria for this equation.
