Existence Conditions for Bounded Solutions of Weakly Perturbed Linear Impulsive Systems

Abstract EN

The weakly perturbed linear nonhomogeneous impulsive systems in the form ẋ=A(t)x + εA1(t)x + f(t), t∈R, t∉T:={τi}Z, Δx|t=τi=γi+εA1ix(τi-), τi∈T⊂R, γi∈Rn, and i∈Z are considered.

Under the assumption that the generating system (for ε=0) does not have solutions bounded on the entire real axis for some nonhomogeneities and using the Vishik-Lyusternik method, we establish conditions for the existence of solutions of these systems bounded on the entire real axis in the form of a Laurent series in powers of small parameter ε with finitely many terms with negative powers of ε, and we suggest an algorithm of construction of these solutions.
