Stability of functional differential equations with impulses [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2007
The authors establish some comparison theorems for functional differential equations (FDE) with impulses using several Lyapunov-Razumikhin. The comparison theorems are employed to develop sufficient conditions for stability theorems for FDE. An example is given to illustrate the usefulness and advantages of the results.

p-Moment stability of functional differential equations with random impulses [PDF]

open access: yesComputers and Mathematics With Applications, 2006
Functional differential equations with random impulses \[ x'(t)= f(t, x_t),\;t\geq t_0,\;t\neq\xi_k,\;x(\xi_k)= I(\tau_k, x(\xi^-_k)),\;k= 1,2,\dots, x_{t_0}= \varphi\tag{1} \] are considered. The following stability conditions were obtained by using Lyapunov's method with Razumikhin condition. Theorem. Let \(x(t)\) be a solution of system (1) and \(p>

Impulsive functional‐differential equations with nonlocalconditions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
The existence, uniqueness, and continuous dependence of a mild solution of an impulsive functional‐differential evolution nonlocal Cauchy problem in general Banach spaces are studied. Methods of fixed point theorems, of a C0 semigroup of operators and the Banach contraction theorem are applied.
