A characterisation of universal minimal total dominating functions in trees
1995
Discrete Mathematics
Preserved Fulltext
A total dominating function (TDF) of a graph G = (V, E) is a function f: V~ [0, 1] such that for each v~ V, ~u~Ntv)f(u)>~ 1, where N(v) denotes the set of neighbours of v. ...
An MTDF whose convex combinations with any other MTDF are minimal is called a universal MTDF. In this paper we characterise universal MTDFs for trees. * Corresponding author. 0012-365X/95/$09.50 ...

We show that any tree that has a universal minimal total dominating function has one which only takes 0-1 values. K 3 demonstrates that this fails for graphs in general. ...
The notion of a total dominating function was first examined in [6] . ...
The algorithm relies on the corresponding result for universal minimal dominating functions to that presented in this paper for total dominating functions, namely that if a tree has a universal, it has ...

In a space-for-time substitution experiment, we assessed changes in organic matter processing and in the functional and taxonomic composition of litter-consuming detritivores along a riparian forest age ...
We found that the decomposition of leaf litter, a component of carbon cycling in forests, was higher in streams flowing through intermediately aged forest, and that several key attributes of the organisms ...
Low decomposition rates are indicative of microbial-dominated decomposition, with a minimal contribution from benthic invertebrate consumers (Boyero et al., 2011) , and hence a low energy turn-over rate ...

In contrast with the notion of complexity, a set A is called anti-complex if the Kolmogorov complexity of the initial segments of A chosen by a recursive function is always bounded by the identity function ...
In this context, we show the equivalence of anti-complexity and other lowness notions such as r.e. traceability or being weak truth-table reducible to a Schnorr trivial set. ...
Since the use function for a total Turing functional is recursive (equivalently, the size of the n th truth-table of a tt-reduction is recursive), there is no uniform notion in this context. ...
