Nuprl Lemma : lpath-members-connected
∀[p:IdLnk List]. ∀[i:ℕ||p||]. ∀[j:ℕi + 1]. lconnects(l_interval(p;j;i);source(p[j]);source(p[i])) supposing lpath(p)
Proof
Definitions occuring in Statement :
lconnects: lconnects(p;i;j)
,
lpath: lpath(p)
,
lsrc: source(l)
,
IdLnk: IdLnk
,
l_interval: l_interval(l;j;i)
,
select: L[n]
,
length: ||as||
,
list: T List
,
int_seg: {i..j-}
,
uimplies: b supposing a
,
uall: ∀[x:A]. B[x]
,
add: n + m
,
natural_number: $n
