Abstract :

In this paper, we discuss a class of second order neutral delay difference equation of the form
egin{equation*}Deltaleft[r(n)left|Delta z(n) ight|^{alpha-1}Delta z(n) ight]+q(n) f(x(n-sigma))=0;quad ngeq n_0quad ag{*}
end{equation*}
where $z(n)=x(n)-p(n)x(n- au)$. We determine sufficient conditions under which every solution of $(*)$ is either oscillatory or tends to zero. Our results improve a number of related results reported in the literature.

Keywords :
