Proof step 3 from proof Sep-forall (previous step)

((aP0 ⊗_ s))(H), ∀ a, H. a ∈ s ∧ aP0(a)(H) → aP(a)(H) ⊦ ((aP ⊗_ s))(H)

User applied rule induction

And obtained the following new goals

Proof step 4:
((aP0 ⊗_ s))(H), ∀ a, H. a ∈ s ∧ aP0(a)(H) → aP(a)(H), ∀ s0, aP0, H, aP. # s0 < # s → ((aP0 ⊗_ s0))(H) ∧ (∀ a, H. a ∈ s0 ∧ aP0(a)(H) → aP(a)(H)) → ((aP ⊗_ s0))(H) ⊦ ((aP ⊗_ s))(H)
