Asymptotic properties of an unstable two-dimensional differential system with delay

Josef Kalas (2006)

Mathematica Bohemica

Similarity:

The asymptotic behaviour of the solutions is studied for a real unstable two-dimensional system $x^{'} (t) = 𝖠 (t) x (t) + 𝖡 (t) x (t - r) + h (t, x (t), x (t - r))$ , where $r > 0$ is a constant delay. It is supposed that $𝖠$ , $𝖡$ and $h$ are matrix functions and a vector function, respectively. Our results complement those of Kalas [Nonlinear Anal. 62(2) (2005), 207–224], where the conditions for the existence of bounded solutions or solutions tending to the origin as $t \to \infty$ are given. The method of investigation is based on the transformation of the real system considered...

We obtain some sufficient conditions for the existence of the solutions and the asymptotic behavior of both linear and nonlinear system of differential equations with continuous coefficients and piecewise constant argument.

Optimal conditions for unique solvability of the Cauchy problem for first order linear functional differential equations

E. Bravyi, Robert Hakl, Alexander Lomtatidze (2002)

Czechoslovak Mathematical Journal

Similarity:

Nonimprovable, in a sense sufficient conditions guaranteeing the unique solvability of the problem $u^{'} (t) = ℓ (u) (t) + q (t), u (a) = c,$ where $ℓ C (I, ℝ) \to L (I, ℝ)$ is a linear bounded operator, $q \in L (I, ℝ)$ , and $c \in ℝ$ , are established.

Properties of solutions of some linear class of integrodifferential equations of Volterra type.

Almost periodic solutions with a prescribed spectrum of systems of linear and quasilinear differential equations with almost periodic coefficients and constant time lag (Fourier transform approach)

Alexandr Fischer (2004)

Mathematica Bohemica

Similarity:

This paper is a continuation of my previous paper in Mathematica Bohemica and solves the same problem but by means of another method. It deals with almost periodic solutions of a certain type of almost periodic systems of differential equations.
