Let $W_{2n}$ be the wheel on $2n+1$ vertices, and let $R(W_{2n})=R(W_{2n},W_{2n})$ denote the diagonal Ramsey number for two copies of this wheel. Six-times-linear wheel conjecture…

Let $C_{2n}$ be the cycle of length $2n$, and let $W_{2n}$ be the wheel on $2n+1$ vertices. Cycle–wheel Ramsey conjecture. … This conjecture would provide the missing exact upper-b…

Let $R(G,H)$ denote the Ramsey number of graphs $G$ and $H$, let $K_{1,m}$ be the star with $m$ leaves, and let $W_{2n}$ be the wheel on $2n+1$ vertices. Li–Schiermeyer’s conjectur…
