| Abstract: | This Paper introduces the definition of the equi-inner transformation of Euclidean space.Then gives four lemmas and two necessary and sufficient conditions of what the linear transformation is the equi-inner transformation.One of the necessary and sufficient conditions hint the matrix relations between the two equi-inner transformation matrices under standard orthogonal basis,the other one hint the relationship between two equi-inner transformations.Finally,the necessary and sufficient condition and a property are derived for infinite dimension Euclidean space is an equi-inner transformation. |
