    We consider an arbitrary periodic operator with a finite number of distant perturbations in an arbitrary domain of a multidimensional space. The perturbations are arbitrary localized operators. We introduce distant perturbations through shift operators, perturbing opera...

    Based on analysis of small temperature disturbances in the Fischer-Tropsch reactor with a fixed bed of catalyst particles various scenarios of thermal instability were investigated. There are two possible scenarios of thermal instability of the reactor. First, thermal e...

    When investigating a behavior of dynamical systems, we should take into account the external noises, which have an effect on the system. The article introduces a concept of the anisotropy-based norm of the system as one of the ways to describe the measure of the effect ...

    <p>The work [1] presents the formulation and numerical solution of the problem concerning the unilateral discrete contact interaction of an elastic body and a rigid half-space. However, many parts and components of engineering structures have a pronounced continuous con...

    <p>The paper studies a dynamical system of globally coupled Rossler oscillators previously con- sidered in terms of oscillation quenching. There are two types of quenching, namely homogeneous steady state and inhomogeneous steady state. A transition from the former to t...

    The paper states a problem and considers two possible methods to estimate the anisotropic norm upper bound for discrete multiplicative noise systems. Shows that standard algorithms of anisotropic norm counting are disabled for multiplicative noise systems. It is impossi...

    <p>The paper provides a qualitative analysis of M.S. Vinogradova's nonlinear model for dynamics of the cell population system. This system describes the stem cells cultivation in vitro under resource constraints. The system consists of two populations, namely: populatio...

    <jats:p>In the paper we consider the Tricomi equation of mixed type. This equation is elliptic in the upper half-plane, hyperbolic in the lower half-plane and parabolically degenerate on the boundary of half-planes. Equations of a mixed type are used in transonic gas dy...

    The paper considers a stability problem of the equilibrium points of dynamical systems of the second order and describes an investigative technique based on the Lyapunov function construction. This method is useful for exploring the equilibrium points, which are exponen...

    The contemporary theory of stability for systems of differential equations is based on the concept of Lyapunov stability, A.M. Lyapunov’s results and their certain generalizations. Analysis of the first approximation of a system is used as a main method to study a stabi...
