Total coloring conjecture on certain classes of product graphs

Electronic Journal of Graph Theory and Applications, 2023
A total coloring of a graph G is an assignment of colors to the elements of the graph G such that no adjacent vertices and edges receive the same color.

Local multiset dimension of comb product of tree graphs

AIMS Mathematics, 2023
<abstract> <p>Resolving set has several applications in the fields of science, engineering, and computer science. One application of the resolving set problem includes navigation robots, chemical structures, and supply chain management. Suppose the set $ W = \left\{{s}_{1}, {s}_{2}, \dots , {s}_{k}\right\}\subset V\left(G\right) $, the ...

Gaudin models and multipoint conformal blocks III: comb channel coordinates and OPE factorisation

Journal of High Energy Physics, 2022
We continue the exploration of multipoint scalar comb channel blocks for conformal field theories in 3D and 4D. The central goal here is to construct novel comb channel cross ratios that are well adapted to perform projections onto all intermediate ...

On fractional metric dimension of comb product graphs

Statistics, Optimization & Information Computing, 2018
A vertex $z$ in a connected graph $G$ \textit{resolves} two vertices $u$ and $v$ in $G$ if $d_G(u,z)\neq d_G(v,z)$. \ A set of vertices $R_G\{u,v\}$ is a set of all resolving vertices of $u$ and $v$ in $G$. \ For every two distinct vertices $u$ and $v$ in $G$, a \textit{resolving function} $f$ of $G$ is a real function $f:V(G)\rightarrow[0,1]$ such ...

Six-point conformal blocks in the snowflake channel

Journal of High Energy Physics, 2020
We compute d-dimensional scalar six-point conformal blocks in the two possible topologies allowed by the operator product expansion. Our computation is a simple application of the embedding space operator product expansion formalism developed recently ...

Odd Harmonious Labeling of P_n ⊵ C₄ and  P_n ⊵ D₂(C₄)

Indonesian Journal of Combinatorics, 2021
A graph G with q edges is said to be odd harmonious if there exists an injection f:V(G) → ℤ2q so that the induced function f*:E(G)→ {1,3,...,2q-1} defined by f*(uv)=f(u)+f(v) is a bijection.Here we show that graphs constructed by edge comb product of ...

On the star partition dimension of comb product of cycle and path [PDF]

AIP Conference Proceedings, 2017
Let G = (V, E) be a connected graphs with vertex set V(G), edge set E(G) and S ⊆ V(G). Given an ordered partition Π = {S1, S2, S3, …, Sk} of the vertex set V of G, the representation of a vertex v ∈ V with respect to Π is the vector r(v|Π) = (d(v, S1), d(v, S2), …, d(v, Sk)), where d(v, Sk) represents the distance between the vertex v and the set Sk ...
