Nuprl Lemma : ring_hom_wf
∀[r,s:RngSig]. (RingHom(r;s) ∈ ℙ)
Proof
Definitions occuring in Statement :
ring_hom: RingHom(R;S),
rng_sig: RngSig,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
ring_hom: RingHom(R;S),
uall: ∀[x:A]. B[x],
member: t ∈ T,
so_lambda: λ2x.t[x],
and: P ∧ Q,
prop: ℙ,
so_apply: x[s]
