In mathematical logic, the ancestral relation (often shortened to ancestral) of a binary relation R is its transitive closure, however defined in a different way, see below.
Ancestral relation - Wikipedia Jump to content From Wikipedia, the free encyclopedia In mathematical logic , the ancestral relation (often shortened to ancestral ) of a binary relation R is its transitive closure , however defined in a different way, see below. Ancestral relations make their first appearance in Frege 's Begriffsschrift . Frege later employed them in his Grundgesetze as part of his definition of the finite cardinals . Hence the ancestral was a key part of his search for a logicist foundation of arithmetic. Definition [ edit ] The numbered propositions below are taken from his B
