• Essential norm
• Composition operator
• Hardy space

The authors give an upper bound of the essential norm of a composition operator on H (2)(B (n) ), which involves the counting function in the higher dimensional value distribution theory defined by S. S. Chern. A criterion is also given to assure that the composition operator on H (2)( (Bn) ) is bounded or compact.
