Nuprl Lemma : lpath-members-connected

[p:IdLnk List]. ∀[i:ℕ||p||]. ∀[j:ℕ1].  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: List int_seg: {i..j-} uimplies: supposing a uall: [x:A]. B[x] add: m natural_number: $n
