The oscillation for a class of even order nonlinear variable delay neutral functional differential equation with damping is discussed. By using the generalized Riccati transformation and the method of H function
and H-lder inequality and some necessary analytic techniques
some new criteria for the oscillation of the equation are proposed. These criteria improve and generalize some corresponding known results. Some examples are given to illustrate the importance of the results.
