GRAPH THEORY { LECTURE 4: TREES 5 The Center of a Tree Review from x1.4 and x2.3 The eccentricity of a vertex v in a graph G, denoted ecc(v), is the distance from v to a vertex farthest from v. That is, ecc(v) = max x2VG fd(v;x)g A central vertex of a graph is a vertex with minimum eccentricity. Materials taken from the Earth have been studied to infer the cycles of past climate. Antarctic ice cores contain trapped air bubbles whose ratios of different oxygen isotopes are a reliable proxy for global temperatures around the time the ice was formed. Study of this data concluded that the climatic response documented in the ice cores was driven by northern hemisphere insolation as …
