Nuprl Lemma : hdf-union-halt
hdf-halt() + hdf-halt() ~ hdf-halt()
Proof
Definitions occuring in Statement :
hdf-union: X + Y,
hdf-halt: hdf-halt(),

hdf-ap: X(a),
hdf-halt: hdf-halt(),
callbyvalueall: callbyvalueall,
evalall: evalall(t),
bag-append: as + bs,
append: as @ bs,
list_ind: list_ind,
bag-map: bag-map(f;bs),
map: map(f;as),
empty-bag: {},
nil: [],
it: ⋅,
btrue: tt,
band: p ∧b q,
ifthenelse: if b then t else f fi
Latex:
