Votes et paradoxes : les élections ne sont pas monotones !

[摘要] The aim of this paper is to illustrate some paradoxes arising from voting theory, in order to elect one person as well as several ones with a system of proportional representation. Based on simple examples, its ambition is to reach a large audience rather than researchers only. Some of these examples exploit the fact that voting procedures are not necessarily monotonous; some others illustrate other kinds of paradoxes.
