Erratum to: 'Oscillation of forced neutral differential equations with positive and negative coefficients' [Comput. Math. Appl. 54(2007)1411-1421]

摘要

In [1], the author studied the oscillation of forced neutral delay differential equations with positive and negative coefficients, having the following form: where R, P, Q ∈ C([t_0, ∞), R~+) with r > 0, τ ≥ σ ≥0. The readers are referred to [1] for further details. The author uses an ill representation which yields a mistake.
