Abstract
AbstractIn this paper, we study the global existence of solutions to some semilinear integro-differential evolution equations in Hilbert spaces with sign-varying kernels. By treating the problem through fixed point theory and energy method, we obtain the global existence theorem on [0, +∞) of mild and strong solution to the evolution equations with memory effects for oscillating and sign-varying kernels. This theorem generalizes and improves some previous existence results.

Abstract: In this paper, we study the global existence of solutions to some semilinear integro-di erential evolution equations in Hilbert spaces with sign-varying kernels. By treating the problem through xed point theory and energy method, we obtain the global existence theorem on [ , +∞) of mild and strong solution to the evolution equations with memory e ects for oscillating and sign-varying kernels.
