对Sierpiński图与Sierpiński gasket图的条件着色进行研究
分别给出其条件色数.对于Sierpiński gasket图
当n≥2时
χ1(Sn)=χ2(Sn)=3
χ3(Sn)=4
若r≥4
则χr(Sn)=6.对于Sierpiński图
若1≤r≤k-1
则χr(S(n
k))=k;若r≥k
k))=k+1.
In this paper
the authors study r-hued coloring of Sierpiński graphs and Sierpiński gasket graphs
meanwhile
the authors give their r-hued chromatic number
respectively. For Sierpiński gasket graphs
when n≥2
χ1(Sn) =χ2(Sn) = 3 and χ3(Sn) = 4; if r≥4
then χr(Sn) = 6. For Sierpiński graphs
if 1≤r≤k- 1
thenχr(S(n
k)) = k; if r≥k
then χr(S(n
k)) = k + 1.
