Base Template DisjointnessOf2Classes


This template expresses that two classes have no members in common (that the classes are disjoint). DisjointnessOf2Classes(x, y) means that the intersection of x and y is empty.

Roles:
1 hasClass1 Class
2 hasClass2 Class

Axiom:

DisjointnessOf2Classes(x1, x2) <-> 
Class(x1) & 
Class(x2) & 
IntersectionOf2Classes(x1, x2, EmptyClass) . 

NOTE See 8.3 for further information on the representation used in this template. See 8.2.1 for a description of the item EmptyClass used in this template.
