      A Fredholm mapping of index zero 

      Soriano Arbizu, José María (Korean Mathematical Society, 2008)
      Sufficient conditions are given to assert that between any two Banach spaces over K Fredholm mappings share exactly N values in a specific open ball. The proof of the result is constructive and is based upon continuation methods.
