Din dicționarul The Free On-line Dictionary of Computing (27 SEP 03) :

  injection
       
          1.  A function, f : A -> B, is injective or
          one-one, or is an injection, if and only if
       
          	for all a,b in A, f(a) = f(b) => a = b.
       
          I.e. no two different inputs give the same output (contrast
          many-to-one).  This is sometimes called an embedding.  Only
          injective functions have left inverses f' where f'(f(x)) = x,
          since if f were not an injection, there would be elements of B
          for which the value of f' was not unique.  If an injective
          function is also a surjection then is it a bijection.
       
          2.  An injection function is one which takes
          objects of type T and returns objects of type C(T) where C is
          some type constructor.  An example is
       
          	f x = (x, 0).
       
          The opposite of an injection function is a projection
          function which extracts a component of a constructed object,
          e.g.
       
          	fst (x,y) = x.
       
          We say that f injects its argument into the data type and fst
          projects it out.
