Proof step 3 from proof owned-emp (previous step)

⊦ !(me, O, emp)(H) ↔ H = ∅

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ !(id, O, P)(H) ↔ P(H) ∧ (∀ r. r ∈ H → O(r) = id)

Rule argument

spec: <toplevel> name: owned seq: ⊦ !(id, O, P)(H) ↔ P(H) ∧ (∀ r. r ∈ H → O(r) = id) subst: [H, P, O, id] → [H, emp, O, me] flags: <all paths>

Additional information

Used simplifier rules: ⊦ emp(H) ↔ H = ∅; (s)% ⊦ ¬ r ∈ ∅; (s) Used terms: H, emp, O, me
