Stability of functional differential equations with variable impulsive perturbations via generalized ordinary differential equations

Bulletin des Sciences Mathématiques, 2013
Abstract We consider a class of functional differential equations with variable impulses and we establish new stability results. We discuss the variational stability and variational asymptotic stability of the zero solution of a class of generalized ordinary differential equations where our impulsive functional differential equations can be embedded ...

Nonlinear Impulsive Differential Equations with Weighted Exponential or Ordinary Dichotomous Linear Part in a Banach Space [PDF]

International Journal of Differential Equations, 2015
We consider nonlinear impulsive differential equations withψ-exponential andψ-ordinary dichotomous linear part in a Banach space. By the help of Banach’s fixed-point principle sufficient conditions are found for the existence ofψ-bounded solutions of these equations onRandR+.

Travelling waves and a fruitful `time' reparametrization in relativistic electrodynamics

, 2018
We simplify the nonlinear equations of motion of charged particles in an external electromagnetic field that is the sum of a plane travelling wave F_t(ct-z) and a static part F_s(x,y,z): by adopting the light-like coordinate ct-z instead of time t as an ...

From regional pulse vaccination to global disease eradication: insights from a mathematical model of Poliomyelitis [PDF]

, 2014
Mass-vaccination campaigns are an important strategy in the global fight against poliomyelitis and measles. The large-scale logistics required for these mass immunisation campaigns magnifies the need for research into the effectiveness and optimal ...

Boundedness and Stability of Impulsively Perturbed Systems in a Banach Space

, 1993
Consider a linear impulsive equation in a Banach space $$\dot{x}(t)+A(t)x(t) = f(t), ~t \geq 0,$$ $$x(\tau_i +0)= B_i x(\tau_i -0) + \alpha_i,$$ with $\lim_{i \rightarrow \infty} \tau_i = \infty $.

Systems of differential equations with implicit impulses and fully nonlinear boundary conditions

Boundary Value Problems, 2013
We show that systems of second-order ordinary differential equations, x″=f(t,x,x′), subject to compatible nonlinear boundary conditions and impulses, have a solution x such that (t,x(t)) lies in an admissible bounding subset of [0,1]×Rn when f satisfies ...

Glycosylated LGALS3BP is highly secreted by bladder cancer cells and represents a novel urinary disease biomarker

Molecular Oncology, EarlyView.
Urinary LGALS3BP is elevated in bladder cancer patients compared to healthy controls as detected by the 1959 antibody–based ELISA. The antibody shows enhanced reactivity to the high‐mannose glycosylated variant secreted by cancer cells treated with kifunensine (KIF).

First-order impulsive ordinary differential equations with advanced arguments

Journal of Mathematical Analysis and Applications, 2007
Consider the boundary value problem \[ x'(t)= f(t, x(t), x(\alpha(t))\quad\text{for }[0,T]\setminus \{t_1,t_2,\dots, t_m\}, \] \[ \Delta x(t_k)= I_k(x(t_k))\quad\text{for }k= 1,\dots, m,\tag{\(*\)} \] \[ 0= g(x(0), x(T)), \] where \(f\), \(\alpha\), \(g\) and \(I_k\) \((1\leq k\leq m)\) are continuous functions, \(0\leq t\leq\alpha(t)\leq T\), \(\Delta
