Finiteness of k-vertex-critical graphs holds in (P4+ℓP1, chair)-free, (P4+ℓP1,P5,bull)-free, (P4+ℓP1,P5,cricket)-free, and more generally (P4+ℓP1,B4(m),B3(m)+)-free graphs, with χ ≤ ℓ+2 for (P4+ℓP1,K3)-free graphs.
Full complexity classification for three b- and fall-coloring problems in H-free graphs plus a separation showing b-Chromatic Number can be NP-hard while Tight b-Chromatic Number is P-time solvable for some H.
