摘要：

In this paper, sufficient conditions for oscillation of unbounded solutions of a class of fourth order neutral delay differential equations of the form (r(t)(y(t)+ p(t)y(t - tau))'')'' + q(t)G(y(t - alpha)) - h(t)H(y(t - sigma)) = 0 are discussed under the assumption integral(infinity)(0) t/r(t)dt = infinity (C) 2020 Mathematical Institute Slovak Academy of Sciences
