Oscillation criteria for a linear neutral differential equation

[摘要] For a neutral differential equation x over dot (t) - a(t) x over dot (g (t)) + b(t)x (h (t)) = 0, 0 less than or equal to a (t) < 1, b (t) greater than or equal to 0, g (t) less than or equal to t, h(t) less than or equal to t, a connection between oscillation properties of the differential equation and differential inequalities is established. Explicit nonoscillation and oscillation conditions and a comparison theorem are presented. (C) 2003 Elsevier Inc. All rights reserved.
