Bilangan Invers Dominasi Total Pada Triangular Snake Graph, Line Triangular Snake Graph, dan Shadow Triangular Snake Graph

open access: yesJambura Journal of Mathematics, 2022
Let G = (V(G), E(G)) be a connected graph, where V(G) is the set of vertices and E(G) is the set of edges. The set Dt(G) is called the total domination set in G if every vertex v 2 V(G) is adjacent to at least one vertex in Dt (G).

Exact Formula and Improved Bounds for General Sum-Connectivity Index of Graph-Operations

open access: yesIEEE Access, 2019
For a molecular graph Γ, the general sum-connectivity index is defined as χβ(Γ) = Σvw∈E(Γ)[dΓ(v) + dΓ(w)]β, where β ∈ R and dΓ(v) denotes the degree of the vertex ...

New results of partially total fuzzy graph

open access: yesBMC Research Notes, 2023
Objective The study of total fuzzy graphs in all cases is crucial for the development of both theories and applications of the graph theory. Without theory the application will not be developed.

Total Weight Choosability of Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
Suppose the edges and the vertices of a simple graph $G$ are assigned $k$-element lists of real weights. By choosing a representative of each list, we specify a vertex colouring, where for each vertex its colour is defined as the sum of the weights of its incident edges and the weight of the vertex itself.

Blind Image Deblurring via Reweighted Graph Total Variation

open access: yes, 2017
Blind image deblurring, i.e., deblurring without knowledge of the blur kernel, is a highly ill-posed problem. The problem can be solved in two parts: i) estimate a blur kernel from the blurry image, and ii) given estimated blur kernel, de-convolve blurry

The sharp bounds on general sum-connectivity index of four operations on graphs

open access: yesJournal of Inequalities and Applications, 2016
The general sum-connectivity index χ α ( G ) $\chi_{\alpha}(G)$ , for a (molecular) graph G, is defined as the sum of the weights ( d G ( a 1 ) + d G ( a 2 ) ) α $(d_{G}(a_{1})+d_{G}(a_{2}))^{\alpha}$ of all a 1 a 2 ∈ E ( G ) $a_{1}a_{2}\in E(G)$ , where

Computing Metric Dimension of Power of Total Graph

open access: yesIEEE Access, 2021
For a connected graph $\mathcal {G}$ , the distance $d(u, v)$ between any two vertices $u$ , $v~\in ~\mathcal {V(G)}$ is defined as; $d(u,v)=\min _{\mathcal {P}_{u,v}}\{\text {length of}~\mathcal {P}_{uv}\}$ i.e the minimum length of path ...

Total coloring of 1-toroidal graphs of maximum degree at least 11 and no adjacent triangles

open access: yes, 2018
A {\em total coloring} of a graph $G$ is an assignment of colors to the vertices and the edges of $G$ such that every pair of adjacent/incident elements receive distinct colors.

Isolation Number of Transition Graphs

open access: yesMathematics
Let G=(V,E) be a graph and F be a family of graphs; a subset (S⊆V(G)) is said to be an F-isolating set if G[V(G)∖NG[S]] does not contain F as a subgraph for all F∈F.

Genus of total graphs from rings: A survey

open access: yesAKCE International Journal of Graphs and Combinatorics, 2018
Let be a commutative ring. The total graph of is the undirected graph with vertex set and two distinct vertices and are adjacent if is a zero divisor in In this paper, we present a survey of results on the genus of and three of its generalizations.
