SZK ⊆ CZK

SZK is contained in CZK.

Statement

Migrated verbatim from computational-zero-knowledge § Known relationships:

Notes

source: folklore: the claim carried no citation on the page it was migrated from, and none was invented.

class: unstated: no citing page says which notion of reduction is meant. Recording a class the wiki does not state would add a claim.

class: free because a containment between complexity classes is proved by any argument at all; the reduction-class axis does not discriminate here, and unstated would wrongly suggest the information is missing.

Recorded during migration and not fixed — these are claims about the source text, not changes to it:

  • No citation and no folklore/standard marker (it is immediate from the definitions).
  • Subject of the sentence is elided (‘Contains SZK’), so direction must be inferred from page context.
