Global solvability for a second order nonlinear neutral delay difference equation

This paper studies the global existence of solutions of the second order nonlinear neutral delay difference equation @D(a"[email protected](x"n+bx"n"-"@t))+f(n,x"n"-"d"""1"""n,x"n"-"d"""2"""n,...,x"n"-"d"""k"""n)=c"n,n>=n"0 with respect to all [email protected]?R. A few results on global existence of uncountably many bounded nonoscillatory solutions are established for the above difference equation. Several nontrivial examples which dwell upon the importance of the results obtained in this paper are also included.
