Let C = (V, E) be an undirected graph, w : E + Z' a weight function and T c V an even subset of vertices from G. A T-cut is an edge-cut set which divides T into two odd sets. For ( Tj = 4 Seymour gave a good characterization of the graphs for which there exists a maximum packing of T-cuts that is in
Let \(G\) be an undirected graph, \(T\) an even subset of vertices and \(F\) an optimal \(T\)-join, which is a forest of two trees. The main theorem of this paper characterizes the cases, where \((G, T)\) has an optimal packing of \(T\)-cuts which is integral. This theorem unifies and generalizes a
