The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Focusing on belief functions in particular, we demonstrate that this very expressive model includes in one sweep many existing models based on probabilities, sets or incomplete preferences. Additionally, we generalize several well-known convergence results from the literature to this broader representational setting.

C2weakest assumption

The assumption that probability sets and lower/upper expected utility gains provide a sufficiently expressive and consistent way to model preferences and strategic decisions without introducing inconsistencies that invalidate the unification or generalizations.

C3one line summary

A new model using probability sets and belief functions unifies existing strategic voting approaches based on probabilities, sets, or incomplete preferences while generalizing convergence results.
