Nuprl - Proof: iter via intseg singleton

IF YOU CAN SEE THIS go to /sfa/Nuprl/Shared/Xindentation_hack_doc.html
Iteration over a singleton is just the value for the one index.

A:Type, f:(A

A), u:A.

is_ident(A; f; u)

(

a,b:

, e:({a..b

}

A). a+1 = b

(Iter(f;u) i:{a..b

}. e(i)) = e(a))

Generated subgoal:

1 1. A : Type
2. f : AAA

4. is_ident(A; f; u)
5. a :
6. b :
7. e : {a..b}A
8. a+1 = b
(Iter(f;u) i:{a..b}. e(i)) = e(a)
