Nuprl Lemma : strictness-add-left

[a:Top]. (⊥ ~ ⊥)


Proof




Definitions occuring in Statement :  bottom: uall: [x:A]. B[x] top: Top add: m sqequal: t
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T has-value: (a)↓ and: P ∧ Q all: x:A. B[x] implies:  Q uimplies: supposing a prop: not: ¬A false: False top: Top
