Almost Periodic Solutions of Evolution Differential Equations with Impulsive Action
Viktor Tkachenko
In an abstract Banach space we study conditions for the existence of piecewise continuous, almost periodic solutions for semi-linear impulsive differential equation with fixed and…
Almost periodic evolution systems with impulse action at state-dependent moments
Robert Hakl, Manuel Pinto, Viktor Tkachenko +1
We study the existence of almost periodic solutions for semi-linear abstract parabolic evolution equations with impulse action at state-dependent moments. In particular, we present…
Global attractivity in almost periodic single species models
Y. M. Myslo, V. I. Tkachenko
Using properties of asymptotically almost periodic solutions we prove existence theorem for piece-wise continuous almost periodic solutions of differential equations with delay and…
A global stability criterion for scalar functional differential equations
E. Liz, V. Tkachenko, S. Trofimchuk
We consider scalar delay differential equations with nonlinear f satisfying a sort of negative feedback condition combined with a boundedness condit…
