Abstract

We study multi-player turn-based games played on a directed graph, where the number of players and vertices can be infinite. An outcome is assigned to every play of the game. Each player has a preference relation on the set of outcomes which allows him to compare plays. We focus on the recently introduced notion of weak subgame perfect equilibrium (weak SPE), a variant of the classical notion of SPE, where players who deviate can only use strategies deviating from their initial strategy in a finite number of histories. We give general conditions on the structure of the game graph and the preference relations of the players that guarantee the existence of a weak SPE, which moreover is finite-memory.

Fußnoten
1
Indexing \(Plays_G\) or \(Hist_G\) with G allows to recall the related game G.
 
2
The limit inferior can be used instead of the limit superior.
 
3
Moore machines are usually defined for finite sets V. We here allow infinite sets V.
 
4
In this article, we will always use notation \(\mu (h\rho )\) instead of \({\mu }_{|{h}}(\rho )\).
 
5
We suppose that \(o \prec _v \top \) for all \(o \in O_L\).
 
6
Ordinal 0 and each limit ordinal are even, and each successor ordinal \(\alpha + 1\) is even (resp. odd) if \(\alpha \) is odd (resp. even).
 
7
When V is finite, it is reached after at most \(2 |O_L| \cdot |V|\) steps.
 
8
The existence of leaves l with a unique outgoing edge (ll) is abusive since the graph is a tree: it should be understood as a unique infinite play from l.
 
9
\(L\) is the prefix-free subset of \(L'\).
