Structural Stability of Autonomous Semilinear Nonlocal Evolution Equations and the Related Semi-dynamical Systems


Our work firstly investigates the unique existence and the continuous dependence (on the singular kernel and initial data) of solutions to nonlocal evolution equations on Hilbert spaces. Secondly, we prove the well-definedness of a related semi-dynamical system consisting of Lipschitz continuous mappings in the space of continuous functions by constructing a metric utilizing the kernel of nonlocal derivative. Our results extend and generalize the existing results on Caputo fractional differential equations, namely the stability and structural stability results in Diethelm and Ford (J. Math. Anal. Appl. 265, 229–248, 2002), the related semi-dynamical systems in Son and Kloeden (Vietnam J. Math. 49, 1305–1315, 2021), to the case of nonlocal differential equations.
