The research objective of this article is to develop an optimal model for a human security system in the Arctic Zone of the Russian Federation (AZRF). This topic has gained particular relevance as the focus of Arctic exploration has shifted to includ

Computationally efficient estimates for the real stability radius of a system matrix are developed for continuous and discrete time systems. The Frobenius norm is used instead of the operator norm and the estimates involve only the stability reserve

where operator A generates C0-semigroup exp(·A). It is well-known [1] that the C0-semigroup gives the solution of (1) by the formula v(t)= exp(tA)v0 for t≥0. We consider the semidiscrete approximation of the problem (1) in the Banach spaces En: v

This article deals with the generalization of Ekeland's first-order necessary conditions of minimum. They are extended to include second-order conditions. The results are applied to variational calculus and mathematical physics.

Numerical procedures for approximate construction of cycles in nonlinear systems are studied. The procedures are based on functional parameter methods combined with mechanical quadratures, Newton's, and gradient methods. The convergence rate of the p
