【摘要】 本文首先给出非正交基下线性算子的外积表示,其次通过引入Gram矩阵给出线性算子在非正交基下矩阵表示和外积表示的系数矩阵之间的关系,再次讨论了非正交基下恒等算子的完备性关系,最后给出了几类线性算子的运算。更多还原

【Abstract】 In this paper,we first give the outer product form of linear operator with respect to the nonorthogonal basis.Then,we introduce the Gram matrix,and give the relationship between the matrix representation and the coefficient matrix.We also discuss the completeness relation for the identity operator.Finally,we give several operations of linear operators.更多还原
