Group inverses of matrices of simple symmetric directed graphs
, 2023 A new class of simple symmetric digraphs called D is defined and studied here. Any digraph in D has the property that each non-pendant is adjacent to at least one pendant vertex.

Study of Cayley Digraphs over Polygroups
MathematicsIn this paper we introduce Cayley digraphs associated to finitely generated polygroups, where the vertices correspond to finite products of the generators of polygroups and the edges to multiplication by vertices and generators.

Interdiction Models and Heuristics for Graph Propagation
Networks, EarlyView.ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Characterizations of Solutions in Digraph Competitions [PDF]
, 2002 The T -measure is introduces as a method to rank the nodes in a digraph competition.It coincides with the T -value of an associated transferable utility game, the so-called digraph game.The T -measure is characterized in two ways.One of them is based on ...

Word Associations in a Minoritised Language: The Case of Cymraeg (Welsh)
International Journal of Applied Linguistics, EarlyView.ABSTRACT As with many research strands in linguistics, word association (WA) literature is dominated by English language data. This paper (i) explores the extent to which methodologies developed to date are applicable to other languages—specifically, Welsh (Cymraeg)—and (ii) investigates what WA analysis can reveal about lexical organisation and ...

International Transactions in Operational Research, EarlyView.Abstract Artificial intelligence (AI)‐enabled digital technologies have the potential to transform agriculture by supporting decision‐making and automating operations. However, their limited adoptions and scholars’ atheoretical explorations constrain our understanding.

The stochastic weighted complexity of a group covering of a digraph
, 2008 We consider the (stochastic) weighted complexity of a digraph D and a stochastic function from A(D) to nonnegative real numbers. Furthermore, we consider the weighted zeta function of a digraph, and present a determinant expression of it.

The The Cayley Graph of Semi-Direct Product of finite Groups: Interrelationships and Construction
Journal of Kufa for Mathematics and ComputerIn this paper, we study Cayley graph of the semi-direct product of two finite groups where is an odd prime numbe. Specifically, we endeavor to establish a comprehensive understanding of the Cayley graph by investigating the interrelationships among ...
