Although there are few results for existence and uniqueness of boundary value problems of sequential fractional derivative by using standart fixed point theorems, such as the method of upper and lower solutions and Schauder fixed point theorem [28], contraction principle [19], the method of upper and lower solutions and its associated monotone iterative method [4], Banach's contraction mapping principle, Krasnoselskii's fixed point theorem and nonlinear alternative of Leray-Schauder type [3, 2], as far as we know there is not much done by using Lyapunov type inequality and disconjugacy criterion.
