Oscillation theorems for first-order nonlinear neutral functional differential equations
From author's abstract: He discusses a class of first-order nonlinear neutral differential equations with variable coefficients and variable deviations. Sharp conditions are established for all solutions to the equations to be oscillatory. Linearized oscillation criteria on the equations are given.
