| adr ∈ as, adr ∈ iast0, iast0 | as ⊆ iast1 ⊦ # as = 0, as = ∅, adr ∈ iast1 |
⊦ iast ⊆ iast0 ↔ (∀ adr. adr ∈ iast → adr ∈ iast0 ∧ iast[adr] = iast0[adr])
adr ∈ iast0, adr ∈ as, ∀ adr. adr ∈ iast0 | as → adr ∈ iast1 ∧ (iast0 | as)[adr] = iast1[adr] ⊦ # as = 0, as = ∅, adr ∈ iast1
Used terms: iast1, iast0 | as
