On the r-dynamic coloring of some fan graph families
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 In this paper, we determine the r-dynamic chromatic number of the fan graph Fm,n and determine sharp bounds of this graph invariant for four related families of graphs: The middle graph M(Fm,n), the total graph T (Fm,n), the central graph C(Fm,n) and the

Effect of White and Yellow Background Colour on Short Term Memory: A Cross-over Study [PDF]
Journal of Clinical and Diagnostic Research, 2021 Introduction: Colour has a potential influence on learning by improving Short Term Memory (STM) in different settings. Background colours of study materials can have an impact on STM in healthy student population. Enhanced memory can improve academic

On the total and AVD-total coloring of graphs
AKCE International Journal of Graphs and Combinatorics, 2020 A total coloring of a graph G is an assignment of colors to the vertices and the edges such that (i) no two adjacent vertices receive same color, (ii) no two adjacent edges receive same color, and (iii) if an edge e is incident on a vertex v, then v and ...

On the total chromatic number of the direct product of cycles and complete graphs
RAIRO Oper. Res.A \textit{$k$-total coloring} of a graph $G$ is an assignment of $k$ colors to the elements (vertices and edges) of $G$ so that adjacent or incident elements have different colors.

Generalized Fractional and Circular Total Colorings of Graphs
Discussiones Mathematicae Graph Theory, 2015 Let P and Q be additive and hereditary graph properties, r, s ∈ N, r ≥ s, and [ℤr]s be the set of all s-element subsets of ℤr. An (r, s)-fractional (P,Q)-total coloring of G is an assignment h : V (G) ∪ E(G) → [ℤr]s such that for each i ∈ ℤr the ...

Total dominator chromatic number of k-subdivision of graphs
The Art of Discrete and Applied Mathematics, 2022 Let $G$ be a simple graph. A total dominator coloring of $G$, is a proper coloring of the vertices of $G$ in which each vertex of the graph is adjacent to every vertex of some color class. The total dominator chromatic (TDC) number $χ_d^t(G)$ of $G$, is the minimum number of colors among all total dominator coloring of $G$.
