Oscillation Theory for Difference and Functional Differential Equations

Oscillation criteria for third-order nonlinear differential equations

“…In fact, in the last few years several monographs and hundreds of research papers have been written, see for example the monographs [1], [2], [7], [15], [16], [17].…”

On the oscillation of third-order quasi-linear delay differential equations

“…Recently, great attention has been devoted to the oscillation of differential equations; see, e.g., the papers [1]- [17]. Especially, differential equations of the form (E) and its special cases have been the subject of intensive research.…”

Oscillation criteria for second order nonlinear neutral differential equations

“…Recently, problems regarding oscillation and nonoscillation for different classes of nonlinear second order differential equations with damping terms attracted attention of many researchers, see, e.g., the monographs [1,2] and the papers [4]- [6], [8], [10]- [11], [13]- [16], [18]- [22] where further references can be found.…”
