Removing Twins in Graphs to Break Symmetries
(MDPI, 2019-11-15)
Determining vertex subsets are known tools to provide information about automorphism groups of graphs and, consequently about symmetries of graphs. In this paper, we provide both lower and upper bounds of the minimum size ...

Characterizing levels of reasoning in graph theory
(Modestum, 2021)
This work provides a characterization of the learning of graph theory through the lens of the van Hiele model. For this purpose, we perform a theoretical analysis structured through the processes of reasoning that students ...

A theoretical analysis of the validity of the Van Hiele levels of reasoning in graph theory
(2022)
The need to develop consistent theoretical frameworks for the teaching and learning of discrete mathematics, specifically of graph theory, has attracted the attention of the researchers in mathematics education. Responding ...

The Equidistant Dimension of Graphs
(Springer, 2022-05-06)
Asubset S of vertices of a connected graphG is a distance-equalizer set if for every two distinct vertices x, y ∈ V(G)\S there is a vertex w ∈ S such that the distances from x and y to w are the same. The equidistant ...
