Nuprl Lemma : same-thread_transitivity

[es:EO]. ∀[p:E ─→ (E Top)].
  ∀[a,b,c:E].  (same-thread(es;p;a;c)) supposing (same-thread(es;p;b;c) and same-thread(es;p;a;b)) 
  supposing causal-predecessor(es;p)


Proof




Definitions occuring in Statement :  same-thread: same-thread(es;p;e;e') causal-predecessor: causal-predecessor(es;p) es-E: E event_ordering: EO uimplies: supposing a uall: [x:A]. B[x] top: Top function: x:A ─→ B[x] union: left right
Lemmas :  same-thread_wf causal-predecessor_wf es-E_wf top_wf event_ordering_wf causal-pred-wellfounded
\mforall{}[es:EO].  \mforall{}[p:E  {}\mrightarrow{}  (E  +  Top)].
    \mforall{}[a,b,c:E].    (same-thread(es;p;a;c))  supposing  (same-thread(es;p;b;c)  and  same-thread(es;p;a;b)) 
    supposing  causal-predecessor(es;p)
