Nuprl Lemma : append-normal-form
∀[A,B:Top]. (rec-case(A) of [] => B | a::_ => r.[a / r] ~ A @ B)
Proof
Definitions occuring in Statement :
append: as @ bs,
list_ind: list_ind,
cons: [a / b],
uall: ∀[x:A]. B[x],
top: Top,
sqequal: s ~ t
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
list_ind: list_ind,
cons: [a / b],
append: as @ bs
Latex:
\mforall{}[A,B:Top]. (rec-case(A) of [] => B | a::$_{}$ => r.[a / r] \msim{} A @ B)
