GRAPH THEORY Prove/Show that a connected Graph G is not separable if and only if it is nonseparable. Definitions for Reference: A connected Graph G is called nonseparable if it has no cut vertices (A vertex v in a connected graph G is caled a cut vertex if G-v is disconnected) A connected graph G is called separable if there exist subgraphs H1, H2 ⊂ G. with E(H1) ∪ E(H2) = E(G) and E(H1) ∩ E(H2) = ∅. V (H1)...
