Neutral Operator and Neutral Differential Equation [PDF]

open access: yesAbstract and Applied Analysis, 2011
In this paper, we discuss the properties of the neutral operator (Ax)(t)=x(t)−cx(t−δ(t)), and by applying coincidence degree theory and fixed point index theory, we obtain sufficient conditions for the existence, multiplicity, and nonexistence of ...

Conditions for Oscillation of a Neutral Differential Equation [PDF]

open access: yesInternational Journal of Differential Equations, 2010
For a neutral differential equation with positive and changeable sign coefficients [x(t)−a(t)x(δ(t))]′+p(t)F(x(τ(t)))−q(t)G(x(σ(t)))=0, oscillation criteria are established, where q(t) is not required as nonnegative. Several new results are obtained.
