Core-Stem Solutions of N-Person Essential Games

摘要

A new wide class of internally stable solutions to essential n-person games in characteristic function form, 'core-stem' solutions, is herein derived based on the notion of 'core of a coalition' and a finite sequence of meta-games (a'stem of games') with a 'stem level' solution for each meta-level. Core-stem solutions exist for every game, can differ according to different stems selected or different stem-level solutions selected. An example with an implausible core and plausible core-stem solution (two different stems) is presented. (Author)
