Proof step 3 from proof lastoc-C-event (previous step)

view(ev) = C, ev ∈ tr0, ∀ view, ev. view(ev) = C ∧ ev ∈ tr0 → (∃ tr2, ev0, tr1. tr0 = tr2 + ev0 ' + tr1 ∧ view(ev0) = C ∧ proj(tr1, Cview(view)) = []) ⊦ ev = ev0, ∃ tr, ev1, tr1. ev0 ' + tr0 = tr + ev1 ' + tr1 ∧ view(ev1) = C ∧ proj(tr1, Cview(view)) = []

Proof step 2:
view(ev) = C, ev ∈ tr0, view(ev) = C ∧ ev ∈ tr0 → (∃ tr2, ev0, tr1. tr0 = tr2 + ev0 ' + tr1 ∧ view(ev0) = C ∧ proj(tr1, Cview(view)) = []) ⊦ ev = ev0, ∃ tr, ev1, tr1. ev0 ' + tr0 = tr + ev1 ' + tr1 ∧ view(ev1) = C ∧ proj(tr1, Cview(view)) = []
