Apr 17, 2020 · I'm never really sure how to prove transitivity when it comes to relations. I know how to disprove transitivity, by simply providing a counter example. For example, in this …

Before talking about the reflexivity, symmetry, transitivity of a relation, first let's talk about binary relations. A binary relation on a set $A$ is simply a subset of the Cartesian product $A \times A$.

There is no need to have multiple copies of the ordered pair to satisfy transitivity (indeed, there shouldn't be, since a relation is a set). Transitivity requires that if $ (a,b)$ and $ (b,c)$ are …

If I have a set of implications, how can I prove the transitivity? In other words: I know the transitivity law, but I need to show on paper for an assignment whether the argument is valid …

Oct 28, 2016 · 0 Recall the definition of transitivity : for all x,y,z in a set A with the relation R, if xRy and yRz then xRz. Now, if we have 2 elements, just think to yourself that our condition …

Reflexivity always requires for the binary relation to include every element of the set, which it may not even if transitivity and symmetry are both valid for the relation. However, it may be …

How can we say we cannot compare between pairs (no completeness) and yet we can have transitivity? Let's assume the relation is a preference relation. For instance if my set has: $(a, …
