A cutting-plane method without inclusions of approximating sets for conditional minimization
Lobachevskii Journal of Mathematics - Tập 36 - Trang 132-138 - 2015
Propose a cutting-plane method with partially embedding of a feasible set for solving a conditional minimization problem. The proposed method is characterized by possibility of periodically dropping of an arbitrary number of any planes constructed in the solution process. Prove convergence of the method, discuss its features, represent assessments of the solution’s accuracy.

Tái cấu trúc các phép đo trong không gian mặt phẳng Dịch bởi AI
Lobachevskii Journal of Mathematics - Tập 32 - Trang 241-246 - 2011
Trong bài báo này, chúng tôi xem xét vấn đề đảo ngược của phương trình tích phân, một vấn đề tự nhiên phát sinh trong lý thuyết các phép đo được sinh ra bởi mật độ cờ (flag densities). Chúng tôi giải quyết phương trình này bằng các phương pháp hình học tích phân và đề xuất một công thức đảo ngược cho mật độ của phép đo trong không gian mặt phẳng dựa trên mật độ cờ của nó.

Homogeneous Hilbert boundary-value problem with several points of turbulence
Lobachevskii Journal of Mathematics - Tập 38 - Trang 414-419 - 2017
We consider Riemann–Hilbert boundary value problem with infinite index in unit disk. Its coefficient is Hölder-continuous everywhere on the unit circle excluding a finite set of points, where its argument has power discontinuities of order less one. The present article is the first research of this version of Hilbert boundary-value problem with infinite index. We obtain formulas for its general so...... hiện toàn bộ
New Type Super Singular Integro-Differential Equation and Its Conjugate Equation
Lobachevskii Journal of Mathematics - Tập 41 - Trang 1123-1130 - 2020
In this paper for a class of model partial integro-differential equation with super singularity in the kernels, is obtained an integral representation of manifold solutions by arbitrary constants. The conjugate equation for the above-mentioned type of equations is also investigated. Such types of integro-differential equations are different from Cauchy-type singular integro-differential equations....... hiện toàn bộ
On the Probability of Finding Marked Connected Components Using Quantum Walks
Lobachevskii Journal of Mathematics - Tập 39 - Trang 1016-1023 - 2018
Finding a marked vertex in a graph can be a complicated task when using quantum walks. Recent results show that for two or more adjacent marked vertices search by quantum walk with Grover’s coin may have no speed-up over classical exhaustive search. In this paper, we analyze the probability of finding a marked vertex for a set of connected components of marked vertices. We prove two upper bounds o...... hiện toàn bộ
On the negative association property for the dependent bootstrap random variables
Lobachevskii Journal of Mathematics - Tập 32 - Trang 32-38 - 2011
In this paper, we prove that the dependent bootstrap random variables possess the negative association property.
Construction of Asymptotic Formulas for Solutions of One Differential Problem with a Singular Coefficient
Lobachevskii Journal of Mathematics - Tập 44 - Trang 3430-3437 - 2023
The first boundary value problem for a second–order differential
operator with a singular potential on a segment with conjugation
conditions at an interior point of the segment is studied. For the
solution of the problem with a parameter, asymptotic formulae and
estimates are obtained on each of the segments of smoothness. A
similar formula is obtained for the solution of the associated
problem.
