$\chi$-binding functions for squares of bipartite graphs and its subclasses

Dibyayan Chakraborty, L. Sunil Chandran, Dalu Jacob +1

A class of graphs $\mathcal{G}$ is $\chi$-bounded if there exists a function $f$ such that $\chi (G)\le f(\omega (G))$ for each graph $G\in \mathcal{G}$, where $\chi (G)$ and $\omega (G)$ are the chro…
