List distinguishing index of graphs
, 2023 We say that an edge colouring breaks an automorphism if some edge is mapped to an edge of a different colour. We say that the colouring is distinguishing if it breaks every non-identity automorphism. We show that such colouring can be chosen from any set of lists associated to the edges of a graph G, whenever the size of each list is at least $Δ-1 ...

Color-blind index in graphs of very low degree [PDF]
, 2015 Let $c:E(G)\to [k]$ be an edge-coloring of a graph $G$, not necessarily proper. For each vertex $v$, let $\bar{c}(v)=(a_1,\ldots,a_k)$, where $a_i$ is the number of edges incident to $v$ with color $i$.

Measuring religious social capital: the scale properties of the Williams Religious Social Capital Index (WRSCI) among cathedral congregations [PDF]
, 2008 The theoretical construct of social capital remains contested in terms of conceptualisation and measurement. The present paper follows the convention of distinguishing between trust, bonding, bridging and linking social capital, to conceptualise how ...

On a Total Version of 1-2-3 Conjecture
Discussiones Mathematicae Graph Theory, 2020 A total k-coloring of a graph G is a coloring of vertices and edges of G using colors of the set {1, . . . , k}. These colors can be used to distinguish adjacent vertices of G. There are many possibilities of such a distinction.

Rectangular Cavity Sensor for Distinguishing Between Normal and High-Drivability-Index Gasolines
IEEE Access, 2020 The Drivability Index (DI) of gasoline is a measure of fuel performance of engine operations. Therefore, distinguishing a gasoline of specific DI in advance is useful for improving engine efficiency and maintenance.

An Improved Upper Bound on Neighbor Expanded Sum Distinguishing Index
Discussiones Mathematicae Graph Theory, 2020 A total k-weighting f of a graph G is an assignment of integers from the set {1, . . . , k} to the vertices and edges of G. We say that f is neighbor expanded sum distinguishing, or NESD for short, if Σw∈N(v) (f(vw) + f(w)) differs from Σw∈N(u)(f(uw) + f(

Social capital and immigrants' labour market performance [PDF]
, 2016 This paper analyses the role of social capital on immigrants’ labour market outcomes. We use the “principal component analysis” (PCA) to build an index of social networks and explore its impact on the probability of getting a job and on wage levels ...

The distinguishing number and the distinguishing index of co-normal product of two graphs
Ratio Mathematica, 2019 The distinguishing number (index) $D(G)$ ($D'(G)$) of a graph $G$ is the least integer $d$ such that $G$ has an vertex labeling (edge labeling) with $d$ labels that is preserved only by a trivial automorphism.

Distinguishing number and distinguishing index of neighbourhood corona of two graphs
Contributions to Discrete Mathematics, 2019 The distinguishing number (index) $D(G)$ ($D'(G)$) of a graph $G$ is the least integer $d$ such that $G$ has an vertex labeling (edge labeling) with $d$ labels that is preserved only by a trivial automorphism. The neighbourhood corona of two graphs $G_1$ and $G_2$ is denoted by $G_1 \star G_2$ and is the graph obtained by taking one copy of ...
