Spectral description of Fredholm operators via polynomially Riesz operators perturbation

Georgian Mathematical Journal, 2022
In this paper, we establish some spectral analysis in Fredholm theory involving the concept of a polynomially Riesz operators perturbation. Moreover, we apply the obtained results to analyze the incidence of some essential spectra of a perturbed operator

On the existence of periodic solutions under the light of semi-Fredholm operators for some evolution equations

Gulf Journal of Mathematics
In this work, we investigate the existence of periodic solutions for a class of evolution equations defined as w(t) = (L + C(t))w(t) + H(t). Sufficient conditions on the family of operators {C(t), t ≥ 0}, L and H are proposed to derive the periodicity of
