On the extremal connective eccentricity index among trees with maximum degree [PDF]
Transactions on Combinatorics, 2021 The connective eccentricity index (CEI) of a graph $G$ is defined as $\xi^{ce}(G)=\sum_{v \in V(G)}\frac{d_G(v)}{\varepsilon_G(v)}$, where $d_G(v)$ is the degree of $v$ and $\varepsilon_G(v)$ is the eccentricity of $v$. In this paper, we characterize the

Assessing sense of community at farmers markets
Journal of Agriculture, Food Systems, and Community Development, 2021 Farmers markets are valuable for reducing food insecurity and delivering healthy food options to populations living with low incomes. However, farmers markets have developed a reputation for being exclusive shopping spaces devoted to affluent, white ...

A Complete Characterisation of Vertex-multiplications of Trees with Diameter 5
Theory and Applications of Graphs, 2021 For a connected graph $G$, let $\mathscr{D}(G)$ be the family of strong orientations of $G$; and for any $D\in\mathscr{D}(G)$, we denote by $d(D)$ the diameter of $D$. The $\textit{orientation number}$ of $G$ is defined as $\bar{d}(G)=\min\{d(D)\mid D\in

Spectral ordering and 2-switch transformations [PDF]
The American Journal of Combinatorics, 2022 We address the problem of ordering trees with the same degree sequence by their spectral radii. To achieve that, we consider 2-switch transformations which preserve the degree sequence and establish when the index decreases.

Conflict-Free Vertex-Connections of Graphs
Discussiones Mathematicae Graph Theory, 2020 A path in a vertex-colored graph is called conflict-free if there is a color used on exactly one of its vertices. A vertex-colored graph is said to be conflict-free vertex-connected if any two vertices of the graph are connected by a conflict-free path ...

Matching-Type Image-Labelings of Trees
Mathematics, 2021 A variety of labelings on trees have emerged in order to attack the Graceful Tree Conjecture, but lack showing the connections between two labelings. In this paper, we propose two new labelings: vertex image-labeling and edge image-labeling, and combine ...

On the Distance Spectral Radius of Trees with Given Degree Sequence
Discussiones Mathematicae Graph Theory, 2020 We consider the problem of maximizing the distance spectral radius and a slight generalization thereof among all trees with some prescribed degree sequence.
