It is observed that the oscillation behaviormay be altered due to presence of the delay. Extensions to forced Emden-Fowler-type delay difference equations Delta(r(n)Delta x(n)) + a(n)vertical bar x(tau n)vertical bar(alpha-1)x(tau n) = b(n); n is an element of N in the sublinear (0 < alpha < 1) and the superlinear (1 < alpha) cases are also discussed.eninfo:eu-repo/semantics/closedAccessnonprincipalforced oscillationdelay difference equationsuperlinearsublinearForced oscillation of delay difference equations via nonprincipal solutionArticleQ141935093520WOS:000432020300020
