Odd Wheels Are Not Odd-distance Graphs [PDF]
Discrete & Computational Geometry, 2020 AbstractAn odd wheel graph is a graph formed by connecting a new vertex to all vertices of an odd cycle. We answer a question of Rosenfeld and Le by showing that odd wheels cannot be drawn in the plane so that the lengths of the edges are odd integers.

Journal of Mathematics and Mathematics Education, 2022 <p>A graph denoted by is a pair of where is a non-empty set of vertices in G, and E is a set of edges in G. In graph theory, there are various types of graphs including star graphs, cycle graph, and wheel graph. Graph operations on two or more types of graphs can produce new graphs. Amalgamation is one of the operations on graphs. Suppose and

A note on the Ramsey numbers for theta graphs versus the wheel of order 5
AKCE International Journal of Graphs and Combinatorics, 2018 The study of exact values and bounds on the Ramsey numbers of graphs forms an important family of problems in the extremal graph theory. For a set of graphs S and a graph F , the Ramsey number R (S , F) is the smallest positive integer r such that for ...

Edge δ− Graceful Labeling for Some Cyclic-Related Graphs
Advances in Mathematical Physics, 2020 In this paper, we introduce a new type of labeling of a graph G with p vertices and q edges called edge δ− graceful labeling, for any positive integer δ, as a bijective mapping f of the edge set EG into the set δ,2δ,3δ,⋯,qδ such that the induced mapping ...

Modular Coloring and Switching in Some Planar Graphs
Ratio Mathematica, 2023 For a connected graph G, let c: V (G) →ℤk (k ≥ 2) be a vertex coloring of G. The color sum \sigma(v) of a vertex v of G is defined as the sum in ℤk of the colors of the vertices in N (v) that is (v) = \sum_{u\inN(v)}{c(u)} (mod k).

Tulgeity of Line, Middle and Total Graph of Wheel Graph Families [PDF]
, 2010 Tulgeity r(G) is the maximum number of disjoint, point induced, non acyclic subgraphs contained in G. In this paper one finds the tulgeity of line, middle and total graph of wheel graph, Gear graph and Helm ...

The spectral determination of the connected multicone graphs
AKCE International Journal of Graphs and Combinatorics, 2021 The main goal of the paper is to answer an unsolved problem. A multicone graph is defined to be the join of a clique and a regular graph, and a wheel as the join of a vertex and a cycle.

Computational Analysis of the Flow Around an Exposed Wheel [PDF]
, 2010 This thesis presents an investigation of RANS and LES models for the isolated rotating exposed wheel with moving ground with the aim of analyzing the flow behavior and comparing the results in cost/quality context. This is motivated by general demand for
