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: b supposing a, 
uall: ∀[x:A]. B[x], 
top: Top, 
function: x:A ⟶ B[x], 
union: left + right
Definitions unfolded in proof : 
uall: ∀[x:A]. B[x], 
member: t ∈ T, 
uimplies: b supposing a, 
all: ∀x:A. B[x], 
implies: P ⇒ Q, 
same-thread: same-thread(es;p;e;e'), 
prop: ℙ
Latex:
\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)
