[Abstract]:As the basis of dynamics, the qualitative properties of differential equations have attracted more and more attention. In recent years, the research of fractional differential equations has become a hot topic. The study of qualitative properties of fractional differential equations has also produced a series of results, among which, the oscillation of fractional differential equations and difference equations has attracted the attention of some experts, and the results are also widely used. In this paper, the oscillatory criteria of fractional differential equation, fractional difference equation and time scale dynamic equation are studied by using generalized Riccati transform and some inequalities based on the previous research methods. This paper is divided into four chapters according to the content: the first chapter is an introduction, mainly introduces the fractional differential equation, fractional difference equation, time scale dynamic equation basic definition properties and Lemma used in this paper. In chapter 2, by using the properties of modified Riemann-Liouville fractional derivative, we study the oscillatory criteria for a class of equations with modified Riemann-Liouville fractional derivative. Where D 偽 X (t) is a modified Riemann-Liouville fractional derivative of order 偽 鈭，
