Flip colouring of graphs II
We give results concerning two problems on the recently introduced flip colourings of graphs, a new class of local v. global phenomena. We prove that for $(b, r)$-flip sequences with $4 \leq b < r < b + 2 \left\lfloor\frac{b+2}{6}\right\rfloor^2$, small constructions of $(b,r)$-flip graphs on...

Zusammenfassung: | We give results concerning two problems on the recently introduced flip
colourings of graphs, a new class of local v. global phenomena. We prove that
for $(b, r)$-flip sequences with $4 \leq b < r < b + 2
\left\lfloor\frac{b+2}{6}\right\rfloor^2$, small constructions of $(b,r)$-flip
graphs on $O(b+r)$ vertices are possible. Furthermore, we prove that there
exists $k$-flip sequences $(a_1, \dots, a_k)$ where $k > 4$, such that $a_k$
can be arbitrarily large whilst $a_i$ is constant for $1 \leq i < \frac{k}{4}$. |
