Baker-Campbell-Hausdorff展开式的一种新方法

A new approach to the Baker-Campbell-Hausdorff expansion

A. V. Bratchikov

摘要:

对于非交换变量x,y,得到log(exp(x)exp(y))的x+y幂展开式,级数的每一项由x-y的无穷次幂和给出,并用图解表示.

英文摘要:

For noncommutative variables x,y an expansion of log(exp(x)exp(y)) in powers of x+y is obtained.Each term of the series is given by an infinite sum in powers of x-y.The series is represented by diagrams.
