2019 The Graph Parameter Hierarchy by Sorge
- page 8 : maximum leaf number upper bounds distance to linear forest by a computable function – Lemma 4.10 ([14]). The max-leaf number $\mathrm{ml}$ upper bounds the distance to disjoint paths $d$. We have $d \le \mathrm{ml}-1$.
assumed
- linear forest upper bounds distance to linear forest by a constant – by definition
- distance to linear forest is equivalent to distance to linear forest – assumed

- distance to linear forest upper bounds pathwidth by a linear function – After removal of $k$ vertices the remaining class has a bounded width $w$. So by including the removed vertices in every bag, we can achieve decomposition of width $w+k$
