Results
- unknown source
- maximum induced matching upper bounds diameter by a linear function – Diameter requires an induced path on $d$ edges, hence, maximum induced matching is at least $\lfloor (d+1)/3 \rfloor$.
- maximum independent set upper bounds maximum induced matching by a linear function – Each edge of the induced matching can host at one vertex of the independent set.
- assumed
- maximum matching upper bounds maximum induced matching by a linear function – By definition
- maximum induced matching is equivalent to maximum induced matching – assumed
