Arnold Inverse Transformation''s Normative Expression and Multi-Dimension Extend
Arnold反变换的规范表达式及多维推广

The periodicity of the Arnold transformation is widely used in image encryption aspect. This transformation is provided with normative expression, but its inverse transformation does not. In this paper, a new normative expression which enable all kinds of Arnold transformation and its inverse transformation formally unify is proposed, in good order and concise, and extend it on multidimensional space as well..
