no im interested in any field.but if you have some examples over C you can post them too of course

 comment An injective smooth function with injective differential must have a continuous inverse?
en.wikipedia.org/wiki/Inverse_function_theorem the fact that the dimension must be the same follows from you assumption that Df(x):R^n -> R^m is invertible(so you can use linear algebra to see that n=m)
