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 .
The term eruv is a shortening of eruv chatzerot (עירוב חצרות ), literally a "merger of [different] domains" (into a single domain). This makes carrying within the area enclosed by the eruv no different from carrying within a single private domain (such as a house owned by an individual), which is permitted.
Agenda building describes the ongoing process by which various groups attempt to transfer their interests to be the interests of public policymakers. [1] Conceptualized as a political science theory by Cobb and Elder in 1971, [2] "the agenda-building perspective...alerts us to the importance of the environing social processes in determining what occurs at the decision-making stage and what ...
More generally, the restriction (or domain restriction or left-restriction) of a binary relation between and may be defined as a relation having domain , codomain and graph ( ) = {(,) ():}. Similarly, one can define a right-restriction or range restriction R B . {\displaystyle R\triangleright B.}
Subjacency is a general syntactic locality constraint on movement.It specifies restrictions placed on movement and regards it as a strictly local process. This term was first defined by Noam Chomsky in 1973 and constitutes the main concept of the Government and Binding Theory.
Domain theory is a branch of mathematics that studies special kinds of partially ordered sets (posets) commonly called domains. Consequently, domain theory can be considered as a branch of order theory .
An example of compartmentalization was the Manhattan Project. Personnel at Oak Ridge constructed and operated centrifuges to isolate uranium-235 from naturally occurring uranium, but most did not know exactly what they were doing. Those that knew did not know why they were doing it.
For example, it is sometimes convenient in set theory to permit the domain of a function to be a proper class X, in which case there is formally no such thing as a triple (X, Y, G). With such a definition, functions do not have a domain, although some authors still use it informally after introducing a function in the form f: X → Y. [2]
