Comments on 'Synchronization and anti-synchronization of new uncertain fractional-order modified unified chaotic systems via novel active pinning control' [Commun Nonlinear Sci Numer Simulat 2010;15:3754-3762]

摘要

In this note some points to paper [L. Pan, W. Zhou.J. Fang, D. Li, Synchronization and anti-synchronization of new uncertain fractional-order modified unified chaotic systems via novel active pinning control, Commun Nonlinear Sci Numer Simulat 2010:15:3754-3762] are presented. Hereby, we illustrate that the way that authors in [1 ] treat with fractional version of Lyapunov stability theorem suffers lack of a correct justification.
