Multiple integral average conditions for oscillation of delay differential equations.
(English)
[J] J. Math. Anal. Appl. 219, No.1, 165-178 (1998). ISSN 0022-247X

The author considers delay differential equations of the form $$x'(t)= \sum^n_{i=1} g_i(t)x(t- T_i(t))= 0,\tag 1$$ with $g_i(t)$, $T_i(t)\in C([t_0,\infty), [0,\infty))$, $t- T(t)\to\infty$ and $t- T_i(t)\to +\infty$ as $t\to\infty$, $i= 1,2,\dots,n$.\par A method based on certain iterative processes is used to obtain some multiple integral average conditions for the oscillation of (1).
