Nuprl Lemma : es-pred-causl
∀the_es:EO. ∀j:E. (pred(j) < j) supposing ¬↑first(j)
Proof
Definitions occuring in Statement :
es-first: first(e),
es-pred: pred(e),
es-causl: (e < e'),
es-E: E,
event_ordering: EO,
assert: ↑b,
uimplies: b supposing a,
all: ∀x:A. B[x],
not: ¬A
Definitions unfolded in proof :
all: ∀x:A. B[x],
member: t ∈ T,
and: P ∧ Q,
uimplies: b supposing a,
guard: {T},
uall: ∀[x:A]. B[x],
implies: P ⇒ Q,
es-causl: (e < e'),
squash: ↓T,
prop: ℙ
Latex:
