  Title: Near identity harmonic maps on sphere must be isometry. 
  Abstract:
  We will explain the proof of the following joint result with B. Chow.
A harmonic map from round n dimensional sphere to itself which is sufficiently close to the identity in the (2, alpha)-norm must be an isometry. The proof employs implication functional theorem.
