Nuprl Lemma : es-before-no_repeats

[es:EO]. ∀[e:E].  no_repeats(E;before(e))


Proof




Definitions occuring in Statement :  es-before: before(e) es-E: E event_ordering: EO no_repeats: no_repeats(T;l) uall: [x:A]. B[x]
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T all: x:A. B[x] strongwellfounded: SWellFounded(R[x; y]) exists: x:A. B[x] nat: implies:  Q false: False ge: i ≥  uimplies: supposing a satisfiable_int_formula: satisfiable_int_formula(fmla) not: ¬A top: Top and: P ∧ Q prop: guard: {T} subtype_rel: A ⊆B decidable: Dec(P) or: P ∨ Q less_than: a < b squash: T no_repeats: no_repeats(T;l) es-before: before(e) sq_type: SQType(T) uiff: uiff(P;Q) ifthenelse: if then else fi  btrue: tt bfalse: ff le: A ≤ B less_than': less_than'(a;b) assert: b iff: ⇐⇒ Q true: True rev_implies:  Q select: L[n] cons: [a b] int_seg: {i..j-} lelt: i ≤ j < k
