This monograph is devoted to a rapidly developing area of research of the qualitative theory of difference and functional differential equations. In fact, in th

Examines developments in the oscillatory and nonoscillatory properties of solutions for functional differential equations, presenting basic oscillation theory a

This monograph explores nonoscillation and existence of positive solutions for functional differential equations and describes their applications to maximum pri

This book summarizes the qualitative theory of differential equations with or without delays, collecting recent oscillation studies important to applications an

With neutral differential equations, any lack of smoothness in initial conditions is not damped and so they have proven to be difficult to solve. Until now, the
