generalized model of judgment and preference aggregation by using trapezoidal fuzzy numbers. Examples are given to illustrate the …

In the theory of judgment aggregation on connected propositions, an important question remains open: Which aggregation … rules are manipulable and which are strategy-proof? We define manipulability and strategy- proofness in judgment aggregation …, characterize all strategy-proof aggregation rules, and prove an impossibility theorem similar to the classic Gibbard …

Judgment aggregation theory, or rather, as we conceive of it here, logical aggregation theory generalizes social choice … theory by having the aggregation rule bear on judgments of all kinds instead of merely preference judgments. It derives from … Mongin. However, the paper also aims at reviewing logical aggregation theory as such, and it covers impossibility theorems by …

In the framework of judgment aggregation, we assume that some formulas of the agenda are singled out as premisses, and … that both Independence (formula-wise aggregation) and Unanimity Preservation hold for them. Whether premiss …-based aggregation thus defined is compatible with conclusion-based aggregation, as defined by Unanimity Preservation on the non …

All existing impossibility theorems on judgment aggregation over logically connected propositions have one of two … logical connections. An important open question is whether judgment aggregation faces any serious impossibilities without …: there exists no judgment aggregation rule satisfying universal domain, collective rationality, anonymity and a new condition …

mathematicien Georges-Théodule Guilbaud has obtained a dictatorship result for the logical problem of aggregation, thus anticipating … the literature on abstract aggregation theory and judgment aggregation. We reconstruct the proof of Guilbaud's theorem …
