Pmean (mu1,mu2)pseudo almost periodic processes and application to
integrodifferential stochastic evolution equations
Moez Ayachi, Syed Abbas
Abstract:
In this article, we investigate the existence and stability of pmean
\((\mu_1,\mu_2)\)pseudo almost periodic solutions for a class of nonautonomous
integrodifferential stochastic evolution equations in a real separable Hilbert space.
Using stochastic analysis techniques and the contraction mapping principle,
we prove the existence and uniqueness of pmean \((\mu_1,\mu_2)\)pseudo almost periodic
solutions. We also provide sufficient conditions for the stability of these solutions.
Finally, we present three examples with numerical simulations to illustrate the
significance of the main findings.
