We further study some known families of valid inequalities for the 2-edge-connected and 2-node-connected subgraph polytopes. For the 2-edge-connected case, we show that the odd wheel inequalities together with the obvious constraints give a complete description of the polytope for Halin graphs. For
## Abstract In this paper are investigated maximum bipartite subgraphs of graphs, i.e., bipartite subgraphs with a maximum number of edges. Such subgraphs are characterized and a criterion is given for a subgraph to be a unique maximum bipartite subgraph of a given graph. In particular maximum bipa
NeSetfil, J. and V. Riidl, On Ramsey graphs without bipartite subgraphs, Discrete Mathematics 101 (1992) 223-229. We prove that for every graph H without triangles and K,,,,,m, n G 2, there exists a Ramsey graph with the same properties. This answers a problem due to Erd& and Faudree. Moreover we
