....colouring of G is a vertex colouring with no bichromatic 4 vertex path; that is, each bichromatic subgraph is a forest of stars. The star chromatic number of G, denoted by # st (G) is the minimum number of colours in a star colouring of G. Acyclic and star colourings have been studied extensively [1 3, 16, 16 20, 52, 53, 63, 85, 86, 86, 99, 113]. By definition # a (G) # st (G) for every graph G. Conversely, if # a (G) c then # st (G) 53] The star chromatic number is bounded for a wide class of graphs. In particular, Nesetril and Ossona de Mendez [99] proved that every proper minor closed graph family has bounded star ....

....of a star and possibly some isolated vertices. The strong star chromatic number of a graph G, denoted by # sst (G) is the minimum number of colours in a strong star colouring of G. Note that star colourings, in which each bichromatic subgraph is a forest of stars, have also been studied (see [20, 34] for example) The star chromatic number of a graph G, denoted by # st (G) is the minimum number of colours in a star colouring of G. With an arbitrary order on each colour class in a strong star colouring, there is no X crossing. Thus track number tn(G) # sst (G) for every graph G, and ....

....colouring of G is a star colouring if there is no bichromatic 4 vertex path; that is, each bichromatic subgraph is a union of disjoint stars. The star chromatic number of G, denoted by st (G) is the minimum number of colours in a star colouring of G. Star colourings have been investigated in [3 5, 8, 12] for example, and are closely related to acyclic colourings and oriented colourings of graphs.
