We consider the problem of fair cost allocation for traveling
salesman games for which the triangle inequality holds. We
give examples showing that the core of such games may be
empty, even for the case of Euclidean distances. On the
positive side, we develop an LP-based ...

We show that, for fixed dimension $n$, the approximation of
inner and outer $j$-radii of polytopes in ${\Re}^n$, endowed
with the Euclidean norm, is polynomial.
The {\it nucleon} is introduced as a new allocation concept for
non-negative cooperative n-person transferable utility games.
The nucleon may be viewed as the multiplicative analogue of
Schmeidler's nucleolus.
It is shown that the nucleon of (not necessarily bipartite) matching
games ...
