Proof step 2 from proof new-ext (previous step)

∀ adr. adr ∈ log → ¬ adr ∈ fs ⊦ new(log, fs)

User applied rule structural induction

And obtained the following new goals

Proof step 3:
∀ adr0. adr0 ∈ adr + log0 → ¬ adr0 ∈ fs, ∀ fs. (∀ adr. adr ∈ log0 → ¬ adr ∈ fs) → new(log0, fs) ⊦ new(adr + log0, fs)

Rule argument

indvar: log
