Should this have its notation made consistent with the implicit funtion theorem page

New example, references

I messed up this article more than a year ago because I confused it with something else. Apparently, nobody noticed. In case anyone was misled, I apologize. I realized my error recently and have made tremendous revisions based on two great references. Teply 02:50, 17 May 2007 (UTC)[reply]

Relationship to Implicit function theorem

How is this related to the implicit function theorem? If that relationship is substantial, I think it should be mentioned on both pages. Dfeuer 17:12, 7 October 2007 (UTC)[reply]

For infinite dimensional Banach spaces, the frechet differential need not be invertible even if it is onto this theorem can still be proved by using quotient spaces.
