From bird flocks to fish schools, animal groups often seem to react to environmental perturbations as if of one mind. Most studies in collective animal behaviour have aimed to understand how a globall...
PATH EXTENSIBILITY OF CONNECTED, LOCALLY 2-CONNECTED K_{1,3}-FREE GRAPHS

摘要 In this paper, we prove that every connected, locally 2-connected claw-freegraph is path extendable.
We show that the two distinct venices u and v of a 2-connected claw-free graph G of order n with minimun degree(n- 2)/3 are [7, n]-panconnected whenever both G-u and G-v are 2-connected.
M. Matthews and D. Sumner proved that if G is a 2-connected claw-free graph of order n, then c(G)\geq \min{2δ + 4, n}. In this paper, we prove that if G is a 2-connected claw-free graph on n venices, ...
