2. Unrestricted domain - Wikipedia

   en.wikipedia.org/wiki/Unrestricted_domain

   In social choice theory, unrestricted domain, or universality, is a property of social welfare functions in which all preferences of all voters (but no other considerations) are allowed. Intuitively, unrestricted domain is a common requirement for social choice functions, and is a condition for Arrow's impossibility theorem .

3. Arrow's impossibility theorem - Wikipedia

   en.wikipedia.org/wiki/Arrow's_impossibility_theorem

   Arrow's theorem assumes as background that any non-degenerate social choice rule will satisfy: [15]. Unrestricted domain — the social choice function is a total function over the domain of all possible orderings of outcomes, not just a partial function.

4. Social Choice and Individual Values - Wikipedia

   en.wikipedia.org/wiki/Social_Choice_and...

   Universal (Unrestricted) Domain U (subsequently so called): Every logically possible set of orderings maps to its own social ordering. Each voter is permitted by the constitution to rank the set of social states in any order, though with only one ordering per voter for a given set of orderings.

5. Voting criteria - Wikipedia

   en.wikipedia.org/wiki/Voting_criteria

   Intuitively, unrestricted domain is a common requirement for social choice functions, and is a condition for Arrow's impossibility theorem. With unrestricted domain, the social welfare function accounts for all preferences among all voters to yield a unique and complete ranking of societal choices.

6. Dictatorship mechanism - Wikipedia

   en.wikipedia.org/wiki/Dictatorship_mechanism

   If there are at least three alternatives, dictatorship is the only ranked voting rule that satisfies unrestricted domain, Pareto efficiency, and independence of irrelevant alternatives. Similarly, by Gibbard's theorem, when there are at least three candidates, dictatorship is the only strategyproof rule.

7. Generic top-level domain - Wikipedia

   en.wikipedia.org/wiki/Generic_top-level_domain

   Unrestricted generic top-level domains are those domains that are available for registration by any person or organization for any use. The prominent gTLDs in this group are com, net, org, and info. However, info was the only one of these, and the first, that was explicitly chartered as unrestricted. The others initially had a specific target ...
