Notes on Binary Dumbbell Trees

Dumbbell trees were introduced in [1]. A detailed description of non-binary dumbbell trees appears in Chapter 11 of [3]. These notes show how binary dumbbell trees can be obtained, and how they can be used to construct, in O(n log n) time, a spanner of bounded degree and weight proportional to O(log n) times the weight of a minimum spanning tree. The reader is assumed to be familiar with the sp...

Sakai and Wardle: Freezing Resistance of New Zealand Trees and Shrubs

Forty-two native woody species were selected to represent the range of temperature-related ecological gradients in New Zealand. Twigs collected in July (mid-winter) were sent by air to Sapporo, Japan, where they were artificially hardened and then tested for freezing resistance. Although only one plant of each species was sampled from each site in anyone year, results were consistent from year ...

Some Notes on Trees and Paths

These notes cover background material on trees which are used in the paper [1]. 1. Trees and paths background information In the paper [1] it is shown that trees have an important role as the negligible sets of control theory, quite analogous to the null sets of Lebesgue integration. The trees considered are analytic objects in flavour, and not the finite combinatorial objects of undergraduate ...
