Impulsive Stabilization of Functional Differential Equations via Liapunov Functionals

open access: yesJournal of Mathematical Analysis and Applications, 1999
The authors discuss the use of the second Lyapunov method and the use of Lyapunov functionals in the analysis of impulsive stabilization problems concerning functional-differential equations of the form \[ x'(t)= f(t, x_t),\quad t\geq t_0,\quad \Delta_x= I_k(t, x(t^-)),\quad t= t_k,\quad k\in \mathbb{Z}^+. \]

Stability results for impulsive functional differential equations with infinite delay [PDF]

open access: yes, 2012
For a family of diff erential equations with in finitive delay and impulses, we establish conditions for the existence of global solutions and for the global asymptotic and global exponential stabilities of an equilibrium point. The results are used to

Oscillations of Higher Order Functional Differential Equations with Impulses [PDF]

open access: yesgmj, 2006
Abstract A kind of higher order sub-and super-linear FDE with impulses is studied in this paper. Several criteria on the oscillations of solutions are given. In particular, in the case where the coefficients of equations are positive and continuous functions, we find some suitable impulse functions such that all solutions of the equation
