an isolated node forms a…
connected component
bridge
the only path between nodes x and y
what would happen if a bridge between nodes x and y was deleted?
the nodes will lie in different components
local bridge
no common friends between x and y
what would happen if a local bridge between x and y was deleted?
the nodes would have a distance > 2
strong triadic closure
if node A has strong ties to B and C, then the B-C edge is likely to form
how does a given node violate STC?
if two of its strong tie nodes are not connected by at least a weak tie
how does a given node satisfy STC?
if two of its strong tie nodes are connected by at least a weak tie
if a node in a network satisfies STC and is involved in at least two strong ties, then…
any strong tie it is involved in cannot be a local bridge and any local bridge it is involved in must be a weak tie
