摘要：
This paper deals with the weak-core of normal form games with a continuum set of players and without side payments. This concept is an approximation of the core introduced by Weber, Shapley and Shubik. The weak-core is slightly larger than Aumann's alpha-core when adapted to large anonymous games. A non-emptiness result is obtained based on the well known Scarfs non-vacuity theorem for finite games. (C) 2010 Elsevier B.V. All rights reserved.
