Nuprl Lemma : pv11_p1_upd_right
∀Cmd:ValueAllType. ∀proposals1,proposals2:(ℤ × Cmd) List. ∀s:ℤ. ∀c:Cmd.
((<s, c> ∈ proposals2) ⇒ (∃c':Cmd. (<s, c'> ∈ pv11_p1_update_proposals(Cmd) proposals1 proposals2)))
Proof
Definitions occuring in Statement :
pv11_p1_update_proposals: pv11_p1_update_proposals(Cmd),
l_member: (x ∈ l),
list: T List,
vatype: ValueAllType,
all: ∀x:A. B[x],
exists: ∃x:A. B[x],
implies: P ⇒ Q,
apply: f a,
pair: <a, b>,
product: x:A × B[x],
int: ℤ
Definitions unfolded in proof :
vatype: ValueAllType,
all: ∀x:A. B[x],
implies: P ⇒ Q,
exists: ∃x:A. B[x],
member: t ∈ T,
iff: P ⇐⇒ Q,
and: P ∧ Q,
rev_implies: P ⇐ Q,
or: P ∨ Q,
prop: ℙ,
uall: ∀[x:A]. B[x],
so_lambda: λ2x.t[x],
so_apply: x[s]
Latex:
