Abstract:In this paper sufficient conditions are obtained so that every solution of

tends to zero or to
as
tends to
, where
are positive real numbers,
, and
,
is non decreasing with
for
. The two primary assumptions in this paper are
and . The results hold when
is linear, super linear,or sublinear and also hold when
. This paper generalizes and improves some of the recent results in [5,7,8,10]. Submitted November 2, 2006. Published January 2, 2007
