  PlanetMath: implicit function theorem
The inverse function theorem is a special case of the implicit function theorem where the dimension of each variable is the same.
This is version 8 of implicit function theorem, born on 2002-08-24, modified 2004-05-25.
I assume it is the derivative with resepect to the jth component of the argument, but it would be nice to have it defined or cross-referenced.

 Manifold - Wikipedia, the free encyclopedia
Viewed using calculus, the circle transition function T is simply a function between open intervals, which gives a meaning to the statement that T is differentiable.
Differentiable manifolds have homeomorphisms on overlapping neighborhoods diffeomorphic with each other, so that the manifold has a well-defined set of functions which are differentiable in each neighborhood, and so differentiable on the manifold as a whole.
As the transition map is a smooth function, this atlas defines a smooth manifold.

 Implicit function theorem - All About All   (Site not responding. Last check: 2007-10-27)
In mathematics, in the field of calculus of several variables, the implicit function theorem says that for a suitable set of equations, some of the variables are defined as functions of the others.
There are some natural limitations on this use of a mathematical relation to define implicit functions, which may be seen in trying to use the unit circle as the graph of a function.
The implicit function is only locally defined, and points at which the first-order behavior would be problematic are outside the scope of the result.
