- feedback edge set upper bounds feedback vertex set by a linear function – Given solution to feedback edge set one can remove one vertex incident to the solution edges to obtain feedback vertex set.
- 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.
