Gabbay's separation theorem, in mathematical logic and computer science, states that any formula of linear temporal logic that includes past-tense operators can be rewritten as a Boolean combination of formulas that each refer only to the past, only to the present, or only to the future. The theorem was stated and proved by the logician Dov Gabbay.

Has Statement Form
Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.
