For example, if f is a binary function symbol and 0 denotes the empty set, then the equivalence f(x; y) ` 0 $ (x ` 0)s(y ` 0) holds but neither of the implica...Kozen, D. (1993), Logical aspects of set constrai

When a field is viewed in IPAM Manage that has a constraint applied, a "check" icon will display next to the field input for simple input constraint checks, if empty values are allowed. If the constraint is of a type that has been set up with a dropdown box, then the dropdown box ...

The display name of this Constraint for use by ToString(). The default value is the name of the constraint with trailing "Constraint" removed. Derived classes may set this to another name in their constructors. (Inherited from Constraint) Or Returns a ConstraintExpression by appending Or to...
We next provide sufficient conditions for which the "strong conical hull intersection property" (strong CHIP) holds, and moreover, we establish necessary and sufficient conditions for characterizing "perturbation property" of the best approximation to any \\(x \\in {\\mathcal {H}}\\) from ...
If a search attempts to search for a column value that violates a check constraint, Oracle will immediately return an empty row set without performing any LIOs. But once again, it can only do so if the check constraint has been validated and set as nondeferrable. See this demo for a 10g...
