Nuprl Lemma : int_dot_cons_nil_lemma
∀as,a:Top. ([a / as] ⋅ [] ~ 0)
Proof
Definitions occuring in Statement :
integer-dot-product: as ⋅ bs,
cons: [a / b],
nil: [],
top: Top,
all: ∀x:A. B[x],
natural_number: $n,
sqequal: s ~ t
Definitions unfolded in proof :
all: ∀x:A. B[x],
member: t ∈ T,
integer-dot-product: as ⋅ bs,
cons: [a / b],
so_lambda: λ2x y.t[x; y],
top: Top,
so_apply: x[s1;s2],
nil: [],
it: ⋅
