With the help of Gromov products coarse trees are described. Complete classification of coarse rays is given, as well as some graphs similar to coarse rays are described. The series of results on balleans, the support of which are groups, are expounded. A Boolean group ideal which fully characterizes a group ballean is studied. The amount of group ideals on countable and Abelean groups is calculated, the lattice of Boolean group ideals is investigated. The application of group balleans to Cech-Stone compactifications of groups is given. The theoretical fundamentals of analysis of stochastic models of modern connection systems within stochastic networks theory, systems with repeated requests and systems with limited queue were developed. The effective algorithms for computing primary characteristics of systems' functioning were developed. The optimizational problems of optimal system parameters and informational flows structure selection were set and solved. Product Description popup.authors popup.nrat_date 2020-04-02 Close
