## What is a partial order relation?

A relation that is reflexive, antisymmetric, and transitive is called a partial order.

Two fundamental partial order relations are the “less than or equal” relation on a set of real numbers and the “subset” relation on a set of sets.

## What are the components of a total order and which one is missing in the definition of a partial order?

A total order is a partial order, but a partial order isn’t necessarily a total order. A totally ordered set requires that every element in the set is comparable: i.e. totality: it is always the case that for any two elements a,b in a totally ordered set, a≤b or b≤a, or both, e.g., when a=b.21 Apr 2013

## What is a strict partial order?

Partial Orders and Strict Partial Orders on Sets. Definition: The relation on the set is said to be a Partial Order on if is reflexive, antisymmetric, and transitive. If is a partial order on then is said to be a Partially Ordered Set with .

## What is a partial order in discrete math?

Partial Orderings

R is a partial order relation if R is reflexive, antisymmetric and transitive. In terms of the digraph of a binary relation R, the antisymmetry is tantamount to saying there are no arrows in opposite directions joining a pair of (different) vertices.
