Abstract:
      In this paper the author transposes the problem of finding the fixed point of an operator T to the same problem of another operator F, provided that the product T· F( = F·T) has an unique fixed point y*, then y* is also the fixed point of T.Using the above result we extend all fixed point theorems with uniqueness.
