利用一元不等式组的解,把含有参数的无穷三对角矩阵描绘成正定矩阵集,再用Hadamard不等式,找到它的精确的零点.可以获得多电子原子和分子Schrdinger方程的严格解析解及其完整的表达式. Using the solution of one-element inequality set, an infinite tridiagonal matrix containing parameters is drawn as a set of positive definite matrices and then Hadamard’s inequality is used to find its exact zero point. A rigorous analytical solution of the multi-electron atom and molecular Schrödinger equations Its complete expression.
