Abstract
We establish some oscillation criteria for the third-order Emden–Fowler neutral delay dynamic equations of the form:
on a time scale \(\mathbb {T}\), where \(\gamma >0\) is a quotient of odd positive integers, and a and p are real-valued positive rd-continuous functions defined on \(\mathbb {T}\). Due to the different values of \(\gamma \), we give not only the oscillation criteria for superlinear neutral delay dynamic equations, but also the oscillation criteria for sublinear neutral delay dynamic equations based on the Hille and Nehari-type oscillation criteria. Our results extend and improve some known results in the literature and are new even for the corresponding third-order differential equations and difference equations as our special cases.
