Oscillations for first order neutral differential equations with variable coefficients
1991
Bulletin of the Australian Mathematical Society
In this paper, sufficient conditions for oscillations of the first order neutral differential equation with variable coefficients (x{t) -cx{t -T))' + p(t)x(t -<T) -q(t)x{t -ft) = 0 are obtained, where c, r , a and y. are positive constants, p, q 6 C([to, oo), R + ) .
