Resumen de Amplitude of weighted majority game strict representations

Josep Freixas Bosch , María Albina Puente del Campo

• Some real situations which may be described as weighted majority games 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
