Abstract

A height-balanced tree is a rooted binary tree T in which for every vertex v@?V(T), the heights of the left and right subtrees of v, differ by at most one. In this paper, we embed two subclasses of height-balanced trees into hypercubes with unit dilation. We also prove that for certain values of p and for all m=1, a complete p^m-ary tree of height h is embeddable into a hypercube of dimension O(mh) with dilation O(m) using the embedding results of the above height-balanced trees. These results improve and extend the results of Gupta et al. (2003) [10].
