| Abstract: | Consider the first order neutral equations with variable coefficients and several deviations of the form The asymptotic behavior of nonoscillatory solutions of the equations is discussed.Necessary and sufficient conditions and several sufficient conditions are obtained for aIl solutions of the equations to be oscillatory. |
