Results

2024 Twin-width of graphs on surfaces by Kráľ, Pekárková, Štorgel
- page 18 : genus upper bounds twin-width by a linear function – The twin-width of every graph $G$ of Euler genus $g \ge 1$ is at most … $18 \sqrt{47g}+O(1)$.
2022 Expanding the Graph Parameter Hierarchy by Tran
- page 34 : bounded c-closure does not imply bounded genus – Proposition 5.6. $c$-Closure is incomparable to Genus.
- page 34 : bounded genus does not imply bounded c-closure – Proposition 5.6. $c$-Closure is incomparable to Genus.
- page 37 : genus upper bounds twin-width by a linear function – Proposition 6.3. Genus strictly upper bounds Twin-width.
- page 37 : bounded twin-width does not imply bounded genus – Proposition 6.3. Genus strictly upper bounds Twin-width.
2019 The Graph Parameter Hierarchy by Sorge
- page 8 : genus upper bounds acyclic chromatic number by a linear function – Lemma 4.8 ([3]). The accylic chromatic number $\chi_a$ is upper bounded by the genus $g$. We have $\chi_a \le 4g+4$.
- page 10 : feedback edge set upper bounds genus by a linear function – Lemma 4.19. The feedback edge set number $f$ upper bounds the genus $g$. We have $g \le f$.
1994 Genus g Graphs Have Pagenumber O(√g) by Malitz
- page 24 : genus upper bounds book thickness by a linear function – Theorem 5.1. Genus $g$ graphs have pagenumber $O(\sqrt{g})$.
assumed
- genus is equivalent to genus – assumed
unknown source
- feedback edge set upper bounds genus by a linear function – Removing $k$ edges creates a forest that is embeddable into the plane. We now add one handle for each of the $k$ edges to get embedding into $k$-handle genus.
- planar upper bounds genus by a constant
- genus upper bounds chromatic number by a linear function – in fact, bounded by square root
Comparing Graph Parameters by Schröder
