Defining rules in cost spanning tree problems through the canonical form
Bergantiños, Gustavo; Vidal-Puga, Juan J. - 2004
We define the canonical form of a cost spanning tree problem. The canonical form has the property that reducing the cost of any arc, the minimal cost of connecting agents to the source is also reduced. We argue that the canonical form is a relevant concept in this kind of problems and study a...

Pairing games and markets
Alkan, Ahmet; Tuncay, Alparslan - 2014
Pairing Games or Markets studied here are the non-two-sided NTU generalization of assignment games. We show that the Equilibrium Set is nonempty, that it is the set of stable allocations or the set of semistable allocations, and that it has several notable structural properties. We also...

On the nonemptiness of approximate cores of large games
Allouch, Nizar; Wooders, Myrna Holtz - 2014
We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...

Size monotonicity and stability of the core in hedonic games
Dimitrov, Dinko; Sung, Shao Chin - 2011
We show that the core of each strongly size monotonic hedonic game is not empty and is externally stable. This is in … sharp contrast to other sufficient conditions for core non-emptiness which do not even guarantee the existence of a stable … set in such games. -- Core ; Hedonic Games ; Monotonicity ; Stable Sets …

The minimal dominant set is a non-empty core-extension
Kóczy, László Á.; Lauwers, Luc - 2003
. The minimal (for inclusion) dominant set is non-empty and for a game with a non-empty coalition structure core, the … minimal dominant set returns this core. …

The γ-core and coalition formation
Chander, Parkash - 2003
This paper reinterprets the γ-core (Chander and Tulkens (1995, 1997)) and justifies it as well as its prediction that … by a coalition, the nonmembers will have incentives to break apart into singletons, as is assumed in the definition of …

The core in the presence of externalities
Kóczy, Lásló À. - 2002
We generalise the coalition structure core to partition function games. Our definition relies only on one crucial … initial one, and – whenever this is possible – they come to a residual core outcome. Deviating players form their optimistic … or pessimistic expectations with this in mind. This leads to a recursive definition of the core. When compared to …
