Differentiability of solutions of abstract neutral integro- differential equations

open access: yesJournal of Integral Equations and Applications, 2013
This work is concerned with the regularity properties of solutions of abstract neutral integro-differential equations with infinite delay. The results are obtained by using a resolvent operator. Some different cases are discussed when the space is reflexive or has the Radon-Nikodym property.
