Nuprl Lemma : for_nil_lemma

∀g,k,f,T:Top.  (For{T,f,k} x ∈ []. g[x] ~ k)


Proof




Definitions occuring in Statement :  for: For{T,op,id} x ∈ as. f[x],  nil: [],  top: Top,  so_apply: x[s],  all: ∀x:A. B[x],  sqequal: s ~ t
Definitions unfolded in proof :  all: ∀x:A. B[x],  member: t ∈ T,  for: For{T,op,id} x ∈ as. f[x],  top: Top
