Proof: given 2 nodes u and v, IF for each pair of paths between u and v there is a common in-between node, there is a GLOBAL common in-between node (a.k.a. articulation point) shared by all paths between u and v
Given 2 nodes u and v, IF for each pair of paths between u and v there is a common in-between node, THEN there is a GLOBAL common in-between node (a.k.a. articulation point) shared by all paths between u and v.
tl;dr does pairwise imply global?
Is this true? Any formal proofs?
