The total H-irregularity strength of triangular ladder graphs
Journal of Physics: Conference Series, 2020 Abstract Let G be a graph which has V(G) as a vertex set and E(G) as an edge set. The G graph contain subgraph H that isomorphic with Hj, j = 1, 2, … s, if every e ∈ E(G) include only in one of the edge set of H subgraph (e ∈ E(H)). The total l-labeling is a graph labeling that give label positive integer number until l into vertices and

The reflexive edge strength on some almost regular graphs
Heliyon, 2021 A function f with domain and range are respectively the edge set of graph G and natural number up to ke, and a function f with domain and range are respectively the vertex set of graph G and the even natural number up to 2kv are called a total k-labeling

Inclusive vertex irregular 1-distance labelings on triangular ladder graphs [PDF]
AIP Conference Proceedings, 2018 For a simple and connected graph G, the distance between two vertices u, v ∈ V (G), denoted by d(u, v), is the length of the shortest path connecting them. A vertex labeling λ: V (G) → {1, …, k} is called an inclusive vertex irregular d-distance labeling if the weights of the vertices are distinct, where the weight of a vertex v is defined as the sum ...

Structure of aluminum atomic chains [PDF]
, 2001 First-principles density functional calculations reveal that aluminum can form planar chains in zigzag and ladder structures. The most stable one has equilateral triangular geometry with four nearest neighbors; the other stable zigzag structure has wide ...

Magnetic and charge susceptibilities in the half-filled triangular lattice Hubbard model
Physical Review Research, 2020 We study the momentum-dependent magnetic and charge susceptibilities in the half-filled two-dimensional triangular Hubbard model within the ladder dual fermion approximation in the metallic, Mott insulating, and crossover regions of parameter space.

On strongly 2-multiplicative graphs [PDF]
Communications in Combinatorics and Optimization, 2020 A simple connected graph $G$ of order $n\ge 3$ is a strongly 2-multiplicative if there is an injective mapping $f :V(G)\rightarrow \{1,2,\ldots,n\}$ such that the induced mapping $h:\mathcal{A} \rightarrow \mathbb{Z}^+$ defined by $h(\mathcal{P})=

A Study on C-Exponential Mean Labeling of Graphs
Journal of Mathematics, 2022 A function h is mentioned as a C-exponential mean labeling of a graph GV,E that has s vertices and r edges if h:VG⟶1,2,3,⋯,r+1 is injective and the generated function h∗:EG⟶2,3,4,⋯,r+1 defined by h∗ab=1/ehbhb/haha1/hb−ha, for all ab∈EG, is bijective.

Spectral Properties of Schr\"odinger Operators on Perturbed Lattices [PDF]
, 2015 We study the spectral properties of Schr\"{o}dinger operators on perturbed lattices. We shall prove the non-existence or the discreteness of embedded eigenvalues, the limiting absorption principle for the resolvent, construct a spectral representation ...

Enhanced Effectiveness in Various Ladder Graphs Based on the F-Centroidal Meanness Criterion
Mathematics, 2023 Graph labeling allows for the representation of additional attributes or properties associated with the vertices, edges, or both of graphs. This can provide a more comprehensive and detailed representation of the system being modeled, allowing for a ...

Effective triangular ladders with staggered flux from spin-orbit coupling in 1D optical lattices [PDF]
The European Physical Journal D, 2020 Light-induced spin-orbit coupling is a flexible tool to study quantum magnetism with ultracold atoms. In this work we show that spin-orbit coupled Bose gases in a one-dimensional optical lattice can be mapped into a two-leg triangular ladder with staggered flux following a lowest-band truncation of the Hamiltonian.
