THE INNOVATIVE INFRASTRUCTURE OF ECONOMIC DEVELOPMENT IN THE FRAMEWORK OF INTERNATIONAL DIGITAL TRANSFORMATION [PDF]
Baltic Journal of Economic Studies, 2018 The development of the innovative digital system, as an important part of the market infrastructure, partly reflects the overall economic level of the country, but its further positive dynamics with the growth of the national economy determines the ...

Breaking the problem into pieces: pre-clustering on-the-fly with the NGLMS
International Journal of Population Data Science, 2017 Objectives The SA.NT DataLink Next Generation Linkage Management System (NGLMS) stores linked data in the form of a graph (in the computer science sense) comprised of nodes (records) and edges (record relationships or similarities).

An algorithm for transitive reduction of an acyclic graph
Science of Computer Programming, 1989 A simple \(0(N^ 3)\) algorithm for computing the transitive reduction of an acyclic digraph is presented. It operates by first computing the transitive closure and then removing in essential arcs. The correctness of the algorithm admits a short proof.

Gauged sigma-models with nonclosed 3-form and twisted Jacobi structures
Journal of High Energy Physics, 2020 We study aspects of two-dimensional nonlinear sigma models with Wess-Zumino term corresponding to a nonclosed 3-form, which may arise upon dimensional reduction in the target space. Our goal in this paper is twofold.

Approximating Transitive Reductions for Directed Networks [PDF]
, 2009 We consider minimum equivalent digraph problem, its maximum optimization variant and some non-trivial extensions of these two types of problems motivated by biological and social network applications. We provide $\frac{3}{2}$-approximation algorithms for all the minimization problems and 2-approximation algorithms for all the maximization problems ...

The dimensional reduction transition [PDF]
Nuclear Physics B, 1985 Abstract If there are more than four space-time dimensions, dimensions small today may have been dynamically important in the evolution of the early universe. The transition to four space-time dimensions may have produced physically significant phenomena observable today.

On solvable minimally transitive permutation groups [PDF]
, 2007 We investigate properties of finite transitive permutation groups (G,O) in which all proper subgroups of G act intransitively on O . In particular, we are interested in reduction theorems for minimally transitive representations of solvable ...

Finite $s$-geodesic-transitive digraphs [PDF]
, 2023 This paper initiates the investigation of the family of $(G,s)$-geodesic-transitive digraphs with $s\geq 2$. We first give a global analysis by providing a reduction result.
