## On forced first order neutral differential equations with positive and negative coefficients.(English)Zbl 0959.34051

Summary: Sufficient conditions are obtained for the oscillation of bounded (unbounded) solutions to a class of forced first-order neutral differential equations with positive and negative coefficients. The techniques used here are different from those used to be employed for such equations earlier.
