Edge-Transitive Lexicographic and Cartesian Products

open access: yesDiscussiones Mathematicae Graph Theory, 2016
In this note connected, edge-transitive lexicographic and Cartesian products are characterized. For the lexicographic product G ◦ H of a connected graph G that is not complete by a graph H, we show that it is edge-transitive if and only if G is edge ...

On transitive one-factorizations of arc-transitive graphs

open access: yes, 2007
It is shown that transitive 1-factorizations of arc-transitive graphs exist if and only if certain factorizations of their automorphism groups exist.

On a Clique‐Building Game of Erdős

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT The following game was introduced in a list of open problems from 1983 attributed to Erdős: two players take turns claiming edges of a Kn ${K}_{n}$ until all edges are exhausted. Player 1 wins the game if the largest clique that they claim at the end is strictly larger than the largest clique of their opponent; otherwise, Player 2 wins the ...

On the Hardness of Switching to a Small Number of Edges

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Seidel's switching is a graph operation which makes a given vertex adjacent to precisely those vertices to which it was non‐adjacent before, while keeping the rest of the graph unchanged. Two graphs are called switching‐equivalent if one can be made isomorphic to the other one by a sequence of switches. Jelínková et al. [DMTCS 13, no. 2, 2011]

A Min–Max Relation on Dicuts and Dijoins in Weighted Chordal Digraphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In a digraph, a dicut is a cut where all the arcs cross in one direction. A dijoin is a subset of arcs that intersects every dicut. Edmonds and Giles conjectured that in a weighted digraph, the minimum weight of a dicut is equal to the maximum size of a packing of dijoins. This has been disproved. However, the unweighted version conjectured by

Modelling Critical Impeding Factors of Gamification Adoption: An ISM‐MICMAC Analysis

open access: yesGlobal Business and Organizational Excellence, EarlyView.
ABSTRACT Gamification is a transformative technology that attracts consumers and motivates them toward desired actions through fun and engagement. Despite its growing popularity and influence on user behavior, gamification faces significant challenges in acceptance and implementation due to behavioral, technological, economic, and regulatory factors ...

Weakly Flag-transitive Configurations and Half-arc-transitive Graphs

open access: yes, 1999
A configuration is weakly flag-transitive if its group of automorphisms acts intransitively on flags but the group of all automorphisms and anti-automorphisms acts transitively on flags.
