Market formation as transitive closure: The evolving pattern of trade in music [PDF]
Network Science, 2015 Where do new markets come from? I construct a network model in which national markets are nodes and flows of recorded music between them are links and conduct a longitudinal analysis of the global pattern of trade in the period 1976–2010.

On Generalized Transitive Matrices
Journal of Applied Mathematics, 2011 Transitivity of generalized fuzzy matrices over a special type of semiring is considered. The semiring is called incline algebra which generalizes Boolean algebra, fuzzy algebra, and distributive lattice.

Merotopies associated with quasi-uniformities
Applied General Topology, 2000 To an arbitrary quasi-uniformity on the set X, a merotopy on X is assigned. There are results concerning the question whether this merotopy is compatible with the topology induced by the quasi-uniformity end whether the closure operation induced by the ...

On Invoking Transitivity to Enhance the
IEEE Access, 2018 From the earliest studies in graph theory, the phenomenon of transitivity has been used to design and analyze problems that can be mapped onto graphs. Some of the practical examples of this phenomenon are the “Transitive Closure”algorithm ...

On the Positive Calculus of Relations with Transitive Closure
Symposium on Theoretical Aspects of Computer Science, 2018 Binary relations are such a basic object that they appear in many places in mathematics and computer science. For instance, when dealing with graphs, program semantics, or termination guarantees, binary relations are always used at some point.

AN ALGORITHM TO COMPUTE THE TRANSITIVE CLOSURE, A TRANSITIVE APPROXIMATION AND A TRANSITIVE OPENING OF A PROXIMITY [PDF]
Computational Intelligence in Decision and Control, 2008 A method to get the transitive closure, a transitive opening and a transitive approximation of a reflexive and symmetric fuzzy relation is presented. The method builds at the same time a binary partition tree for the output similarities.

Spatiality of Derivations of Operator Algebras in Banach Spaces
Abstract and Applied Analysis, 2011 Suppose that A is a transitive subalgebra of B(X) and its norm closure A¯ contains a nonzero minimal left ideal I. It is shown that if δ is a bounded reflexive transitive derivation from A into B(X), then δ is spatial and implemented uniquely; that is ...

Tiling arbitrarily nested loops by means of the transitive
International Journal of Applied Mathematics and Computer Science, 2016 A novel approach to generation of tiled code for arbitrarily nested loops is presented. It is derived via a combination of the polyhedral and iteration space slicing frameworks. Instead of program transformations represented by a set of affine functions,

Lattice structure of Grassmann-Tamari orders [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 The Tamari order is a central object in algebraic combinatorics and many other areas. Defined as the transitive closure of an associativity law, the Tamari order possesses a surprisingly rich structure: it is a congruence-uniform lattice.
