Proof
Definitions occuring in Statement :
VesleySchema: VesleySchema,
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
VesleySchema: VesleySchema,
member: t ∈ T,
uall: ∀[x:A]. B[x],
subtype_rel: A ⊆r B,
prop: ℙ,
so_lambda: λ2x.t[x],
implies: P ⇒ Q,
all: ∀x:A. B[x],
nat_plus: ℕ+,
so_apply: x[s],
uimplies: b supposing a,
le: A ≤ B,
and: P ∧ Q,
less_than': less_than'(a;b),
false: False,
