 Title OSCILLATION OF NONLINEAR NEUTRAL DELAY DIFFERENTIAL EQUATION WITH SEVERAL COEFFICIENTS Publication Type Journal Article Year of Publication 2010 Authors YILDIZ MUSTAFAKEMAL Journal Dynamic Systems and Applications Volume 19 Start Page 199 Pagination 11 Date Published 2010 ISSN 1056-2176 AMS Subject Classification 34C10, 34K40, 34K99 Abstract In this article, we show that the oscillation of all solutions to the neutral equation [x (t) − R (t) N (x (t − κ))]′ + Xn i=1 Pi (t) Fi (x (t − τi)) − Xm j=1 Qj (t) Gj (x (t − σj )) = 0 is implied by the oscillation of all solutions to the linear equation [x (t) − rx (t − κ)]′ + Xn i=1 pix (t − τi) − Xm j=1 qjx (t − σj ) = 0. In these equations, R,Pi , Qj are positive and continuous functions, and κ, τi , σj are positive constants that represent delays PDF https://acadsol.eu/dsa/articles/19/15-DSA-239.pdf Refereed Designation Refereed
