In this note we improve significantly the result appeared in [4] by showing that any sequence of trees { T2, 'I;, . , T,} can be packed into the complete bipartite graph K,\_,,n,z (n even) for f = 0.3n. Furthermore we support Fishburn's Conjecture [2] by showing that any sequence {T,, T4,
For two integers a and b, we say that a bipartite graph G admits an (a, b)bipartition if G has a bipartition (X, Y ) such that |X| = a and |Y | = b. We say that two bipartite graphs G and H are compatible if, for some integers a and b, both G and H admit (a, b)-bipartitions. In this paper, we prove
## Abstract In this study, we provide methods for drawing a tree with __n__ vertices on a convex polygon, without crossings and using the minimum number of edges of the polygon. We apply the results to obtain planar packings of two trees in some specific cases. Β© 2002 Wiley Periodicals, Inc. J Grap
For two bipartite graphs G = (L, R; E) and G' = (L', R'; E') a bijection f: LwR --\* L'uR' such that f(L) = L' is called hi-placement when f(u)f(v)~E', for every edge uv ~ E (then G and G' are called hi-placeable). We give new sufficient conditions for bipartite graphs G and G' to be bi-placeable.
