On the P3-hull numbers of q-Kneser graphs and Grassmann graphs

作者:

Highlights:

• We compute the exact value of -hull numbers of -Kneser graphs, which is the minimum size of a vertex set that eventually infects the whole graph.

• We compute the exact value of -hull numbers of Grassmann graphs.

• Recently, Grippo et al. studied the -hull number of Kneser graphs, we generalized their results to vector spaces.
