Proof step 17 from proof lastoc-C-event (previous step)

viewvar(ev) = C, ev ∈ tr ⊦ ∃ tr0, ev0, tr1. tr = tr0 + ev0 ' + tr1 ∧ viewvar(ev0) = C ∧ proj(tr1, Cview(viewvar)) = []

User applied rule induction

And obtained the following new goals

Proof step 16:
viewvar(ev) = C ∧ ev ∈ tr, ∀ tr0, viewvar, ev. # tr0 < # tr → (viewvar(ev) = C ∧ ev ∈ tr0 → (∃ tr2, ev0, tr1. tr0 = tr2 + ev0 ' + tr1 ∧ viewvar(ev0) = C ∧ proj(tr1, Cview(viewvar)) = [])) ⊦ ∃ tr0, ev0, tr1. tr = tr0 + ev0 ' + tr1 ∧ viewvar(ev0) = C ∧ proj(tr1, Cview(viewvar)) = []

Rule argument

[INDHYPARG : [STANDARDINDUCTIONTYPE : ], true, false, # tr, [] → [], <]
