MAXIMUM CUTS IN GRAPHS WITHOUT WHEELS
Bulletin of the Australian Mathematical Society, 2018For a graph $G$, let $f(G)$ denote the maximum number of edges in a bipartite subgraph of $G$. Given a fixed graph $H$ and a positive integer $m$, let $f(m,H)$ denote the minimum possible cardinality of $f(G)$, as $G$ ranges over all graphs on $m$ edges that contain no copy of $H$. Alon et al.

Binding Number and Wheel Related Graphs
International Journal of Foundations of Computer Science, 2017The binding number of a graph G is defined to be the minimum of [Formula: see text] taken over all nonempty [Formula: see text] such that [Formula: see text]. Binding number, one indicator to better understand graph, is an important characteristic quantity of a graph.

Extremal graphs for odd wheels
Journal of Graph Theory, 2021AbstractFor a graph , the Turán number of , denoted by ex, is the maximum number of edges of an ‐vertex ‐free graph. Let denote the maximum number of edges not contained in any monochromatic copy of in a 2‐edge‐coloring of . A wheel is a graph formed by connecting a single vertex to all vertices of a cycle of length .

The Mathematics Teacher, 2019
To introduce sinusoidal functions, I use an animation of a Ferris wheel rotating for 60 seconds, with one seat labeled You (see fig. 1). Students draw a graph of their height above ground as a function of time with appropriate units and scales on both axes. Next a volunteer shares his or her graph. I then ask someone to share a different graph.

Hub number of some wheel related graphs
2020Summary: A hub set in a graph \(G\) is a set \(S\subseteq V(G)\) such that any two vertices outside \(S\) are connected by a path all of whose internal vertices are members of \(S\). The minimum cardinality of a hub set is called hub number. In this paper, we give results for the hub number of some wheel related graphs.

Hamilton Cycle on the Wheel Graph
Journal of Mathematical Sciences and OptimizationThis article discusses the existence of the Hamilton cycle in the wheel graph by constructing steps to find the existence of the Hamilton cycle. A graph that has a Hamilton cycle is called a Hamilton graph, A circle graph is a graph where each vertex has a degree of two, denoted by Cn.
