Nuprl Lemma : rset-neg_wf
∀[A:Set(ℝ)]. (-(A) ∈ Set(ℝ))
Proof
Definitions occuring in Statement :
rset-neg: -(A),
rset: Set(ℝ),
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
rset-neg: -(A),
rset: Set(ℝ),
rset-member: x ∈ A,
uall: ∀[x:A]. B[x],
member: t ∈ T,
all: ∀x:A. B[x],
implies: P ⇒ Q,
subtype_rel: A ⊆r B,
prop: ℙ,
uimplies: b supposing a,
uiff: uiff(P;Q),
and: P ∧ Q,
rev_uimplies: rev_uimplies(P;Q)
