Now let abc, bcd be odd triangles, we claim a, b, c start from the same point of H. Suppose indirectly that a, b, c form a triangle of H. By definition, there is an edge x adjacent to one or three of a, b, c. But this is impossible since x must start from a point of the triangle formed by a, b, c in H and so, x is adjacent to two of a, b, c. Thus a starts from the common point of b, c. Similarly, d starts from the common point of b, c implying that a, d are adjacent. (b) We may assume that G is connected since each component satisfies (i) and (ii) and if they are line-graphs, then so is G. Let (a, b) ∼ (c, d) be as in the hint. Suppose that (a, b) ∼ (c, d) ∼ (e, f ) are distinct edges of G, we show that (a, b) ∼ (e, f ) (the other criteria for an equivalence relation are trivially fulfilled). Observe that {a, b, c, d} spans a complete graph. Consider a and e (say), a ̸= e. If a = c or d, then a, e are trivially adjacent so suppose that a ̸= c, d; similarly e ̸=

We show that G0 can be embedded into a critically (k + 1)-chromatic graph even as an induced subgraph. The assumption means that for each e ∈ E(G0 ), there exists a k-coloration αe of S = V (G0 ) that associates the same color with the endpoints of e, but different colors with the endpoints of any other edge of G0 . Let Pe be the partition of S induced by αe . By 9.8, we can find a graph G such that S ⊆ V (G) and the k-colorations of G induce the partitions Pe (e ∈ E(G0 )) of S and no other partition. Set G′ = G ∪ G0 .” 9.56 Insert at the end of the solution: “The converse is easy: assume that the graph has a 3-coloring with red, blue and green, and consider any node v with color red (say).

E(G1 · G2 ) = {((x1 , x2 ), (y1 , y2 ) : (x1 , y1 ) ∈ E(G1 ) and (x2 , y2 ) ∈ E(G2 ), or x1 = y1 and (x2 , y2 ) ∈ E(G2 ) or (x1 , y1 ) ∈ E(G1 ) and x2 = y2 }.
