90 minutes (including discussion)
The talk aims to review the seminal articles that gave rise to these values for cooperative games and these power indices for simple games. The main arguments that support them are the axiomatic characterizations and the respective probabilistic approaches. On this basis, arguments and difficulties will be presented for their appropriate extension to multichoice cooperative games and voting games with several levels of approval.
