摘要
We give a complete structure description of (P-5,gem)-free graphs. By the results of a related paper, this implies bounded clique width for this graph class. Hereby, as usual, the P5 is the induced path with five vertices a, b, c, d, e and four edges ab, bc, cd, de, and the gem consists of a P-4 a, b, c, d with edges ab, be, cd plus a universal vertex e adjacent to a, b, c, d.
