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 ...
