Abstract:

Necessary and sufficient conditions are obtained for every solution of

$Delta left( {y_n + p_n y_n - m} right) pm q_n G(y_n - k) = f_n$

to oscillate or tend to zero as n rarr

, where p_n, q_n and f_n are sequences of real numbers such that q_n

0. Different ranges for p_n are considered.
