Abstract:This paper studies the oscillation of a class of second-order differential equations with a nonlinear neutral term and a damping term. By using the generalized Riccati transformation and inequality technique,two new oscillation theorems for the equations above are obtained,thus extending and improving some known results in the literature.
Key words:oscillation; nonlinear neutral term; neutral differential equations
