The stability and asymptotic stability of the solutions of large-scale linear impulsive systems under structural perturbations
are investigated. Sufficient conditions for stability and instability are formulated in terms of the fixed signs of special
matrices.

Аналіз стійкості лінійних диференціальних імпу льсних систем із структурними зБуреннями
Досліджуються стійкість та асимптотична стійкість возв'язків великомасштабної лінійної імпульсної системи при структурних збуреннях. Достатні умови стійкості та нестійкості сформульовані на основі знаковизначеності спеціальних матриць.

Let be the -partite multigraph in which each part has size , where two vertices in the same part or different parts are joined by exactly edges or edges, respectively. It is proved that there exists a maximal set of edge-disjoint Hamilton cycles in for , the upper bound being best possible. The results proved make use of the method of amalgamations. 相似文献

Let be the finite field of q elements and let be the dihedral group of 2n elements. Left ideals of the group algebra are known as left dihedral codes over of length 2n, and abbreviated as left -codes. Let . In this paper, we give an explicit representation for the Euclidean hull of every left -code over . On this basis, we determine all distinct Euclidean LCD codes and Euclidean self-orthogonal codes which are left -codes over . In particular, we provide an explicit representation and a precise enumeration for these two subclasses of left -codes and self-dual left -codes, respectively. Moreover, we give a direct and simple method for determining the encoder (generator matrix) of any left -code over , and present several numerical examples to illustrative our applications. 相似文献
