==Beatpath Order==
The Schwartz set is the union of all of the cycle equivalence classes that are [http://en.wikipedia.org/wiki/Maximal_element maximal] in the [[../Beatpath#beatpath_orderBeatpath_order | beatpath order]]. A set is a Schwartz set component if and only if it is a [[../Beatpath#Cycle_equivalence | cycle equivalence class]] that is maximal in the beatpath order.
 
This characterization of the Schwartz set follows from two characteristics of any set S that fullfills the first property of a Schwartz set component:

Other characteristics of the Schwartz set include:
 
* If a [[Condorcet Criterion |Condorcet winner]] exists, it is the one and only candidate in the Schwartz set.
 
* All [http://en.wikipedia.org/wiki/Condorcet_method#Related_terms weak Condorcet winners] are in the Schwartz set. The weak Condorcet winners are the candidates in the Schwartz set that are not in a cycle, i.e. they are each in their own Schwartz set component.
