For example, sociological, ecological or economical perspectives are used to view the interrelationships between the individual, their relatives, and the historical time. [1] The study of ...
For example, "is a blood relative of" is a symmetric relation, because x is a blood relative of y if and only if y is a blood relative of x. Antisymmetric for all x, y ∈ X, if xRy and yRx then x = y. For example, ≥ is an antisymmetric relation; so is >, but vacuously (the condition in the definition is always false). [11] Asymmetric

The Ancestral relation is equal to the transitive closure + of .Indeed, is transitive (see 98 above), contains (indeed, if aRb then, of course, b has every R-hereditary property that all objects x such that aRx have, because b is one of them), and finally, is contained in + (indeed, assume ; take the property to be +; then the two premises, () and (), are obviously satisfied; therefore ...
