Avtor v etom svojem esse zanimajetsja poslednim desjatiletijem ukrainskoj literatury v svjazi s vozniknovenijem Ukrainy kak samostojatel'nogo gosudarstva. Obraščajetsja zdes' vnimanije na te elementy literaturnogo processa, kotoryje okazali vlijanije na poiski novoj identičnosti sovremennoj ukrainskoj literatury.
Let H be a finite abelian group of odd order, D be its generalized dihedral group, i.e., the semidirect product of C2 acting on H by inverting elements, where C2 is the cyclic group of order two. Let Ω (D) be the Burnside ring of D, Δ(D) be the augmentation ideal of Ω (D). Denote by Δn(D) and Qn(D) the nth power of Δ(D) and the nth consecutive quotient group Δn(D)/Δn+1(D), respectively. This paper provides an explicit Z-basis for Δn(D) and determines the isomorphism class of Qn(D) for each positive integer n., Shan Chang., and Obsahuje seznam literatury
Deterministic measures of stability are used for some parameters of graphs as connectivity, covering number, independence number and dominating number. For a long time, in the graph theory any vertex is considered with its neighbourhood. By means of this idea, we define the accessible set and the accessibility number of a connected graph. In this paper we search the accessibility number and other parameters of augmented cubes.
In this paper, the augmented Lagrangian method is investigated for solving recourse problems and obtaining their normal solution in solving two-stage stochastic linear programming problems. The objective function of stochastic linear programming problem is piecewise linear and non-differentiable. Therefore, to use a smooth optimization methods, the objective function is approximated by a differentiable and piecewise quadratic function. Using quadratic approximation, it is required to obtain the least 2-norm solution for many linear programming problems in each iteration. To obtain the least 2-norm solution for inner problems based on the augmented Lagrangian method, the generalized Newton method is applied.
