Title: Oscillation of solutions for odd-order
       neutral functional differential equations
       
Author: Tuncay Candan (Nigde Univ., Nigde, Turkey)

Abstract: 
 In this article, we establish oscillation criteria
 for all solutions to the neutral differential equations
 $$
 [x(t)\pm ax(t\pm h)\pm bx(t\pm g)]^{(n)}
 =p\int_c^d x(t-\xi)d\xi+q\int_c^d x(t+\xi)d\xi,
 $$
 where $n$ is odd, $h$, $g$, $a$ and $b$ are nonnegative
 constants. We consider 10 of the 16 possible combinations
 of +/- signs, and give some examples to illustrate our results.
