AMPLITUDE OF WEIGHTED MAJORITY GAME STRICT REPRESENTATIONS

Some real situations which may be described as weighted majority ga-mes can be modified when some players increase or decrease their weights and/or the quota is modified. Nevertheless, some of these modifications do not change the game. In the present work we shall estimate the maximal percentage variations in the weights and the quota which may be allowed without changing the game (amplitude). For this purpose, we have to use strict representations of weighted majority games
