Asymptotically almost periodic solutions for a class of integrodifferential equations governed by a Hille-Yosida operator with non-dense domain.
摘要
The primary objective of this work is to develop a new variation of a constant formula for a class of integrodifferential equations with a non-dense domain. Using this formula with a new composition theorem of Stepanov asymptotically almost periodic functions, we prove the existence of asymptotically almost periodic integral solutions for a specific class of integrodifferential equations with a non-dense domain, where the forcing term is only asymptotically almost periodic in the weak (Stepanov) sense.
