Suppose <math>G</math> is any graph and <math>T</math> is a tree whose vertices | Suppose <math>\,G</math> is any [[graph, undirected graph, nonoriented graph|graph]] and <math>\,T</math> is a [[tree]] whose [[vertex|vertices]] — call them ''[[node|nodes]]'' to help avoid confusing them with the vertices of <math>\,G</math> — are precisely the ''[[maxclique|maxcliques]]'' of <math>\,G</math>. For every <math>\,v \in V(G)</math>, let <math>\,T_{v}</math> denote a [[subgraph]] of <math>\,T</math> induced by those nodes that contain <math>\,v</math>. If every such <math>\,T_{v}</math> is connected — in other words, if every <math>\,T_{v}</math> is a [[subtree]] of <math>\,T</math> — then call <math>\,T</math> a '''clique tree''' for <math>\,G</math>. | ||
