Impulsive system of ODEs with general linear boundary conditions [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
The paper provides an operator representation for a problem which consists of a system of ordinary differential equations of the first order with impulses at fixed times and with general linear boundary conditions \begin{gather} z'(t) = A(t)z(t) + f(t,z ...

APPROXIMATION OF POSITIONAL IMPULSE CONTROLS FOR DIFFERENTIAL INCLUSIONS

open access: yesUral Mathematical Journal, 2022
Nonlinear control systems presented as differential inclusions with positional impulse controls are investigated. By such a control we mean some abstract operator with the Dirac function concentrated at each time. Such a control ("running impulse"), as a

On Exact Controllability of First-Order Impulsive Differential Equations

open access: yesAdvances in Difference Equations, 2010
Many dynamical systems have an impulsive dynamical behavior due to abrupt changes at certain instants during the evolution process. The mathematical description of these phenomena leads to impulsive differential equations.

Asymptotic construction of pulses in the Hodgkin Huxley model for myelinated nerves [PDF]

open access: yes, 2005
A quantitative description of pulses and wave trains in the spatially discrete Hodgkin-Huxley model for myelinated nerves is given. Predictions of the shape and speed of the waves and the thresholds for propagation failure are obtained.

The remarkable effectiveness of time-dependent damping terms for second order evolution equations [PDF]

open access: yes, 2015
We consider a second order linear evolution equation with a dissipative term multiplied by a time-dependent coefficient. Our aim is to design the coefficient in such a way that all solutions decay in time as fast as possible.

Eventual stability and eventual boundedness for impulsive differential equations with “supremum”

open access: yesMathematical Modelling and Analysis, 2011
Eventual stability and eventual boundedness for nonlinear impulsive differential equations with supremums are studied. The impulses take place at fixed moments of time. Piecewise continuous Lyapunov functions have been applied.

On the existence of periodic solution of some quasilinear differential equations with impulses

open access: yesVietnam Journal of Mechanics, 2004
As for ordinary differential equations, one of the problems that especially attract the attention of many mathematicians is the problem on the existence of periodic solutions of the differential equation systems with impulses.

Multiple Periodic Solutions and Fractal Attractors of Differential Equations with n-Valued Impulses

open access: yesMathematics, 2020
Ordinary differential equations with n-valued impulses are examined via the associated Poincaré translation operators from three perspectives: (i) the lower estimate of the number of periodic solutions on the compact subsets of Euclidean spaces and, in ...
