Radio de estabilidad real de sistemas bidimensionales para perturbaciones lineales dependientes del tiempo.
Razumikhin stability theorem for fractional systems with delay.
Razumikhin's method in the qualitative theory of processes with delay.
Relationship between different types of stability for linear almost periodic systems in Banach spaces.
Remarque sur la stabilité dans le cas d'une équation linéaire à paramètre retardé avec une perturbation non linéaire
Robust stability and stabilization of a class of uncertain nonlinear systems with delays.
Robustness with respect to small time-varied delay for linear dynamical systems on Banach spaces
Under suitable conditions we prove the wellposedness of small time-varied delay equations and then establish the robust stability for such systems on the phase space of continuous vector-valued functions.
