摘要:
设X和Y是两个n × n的埃尔米特矩阵。在文章“证明一个简化的指数公式“(Linear and多重线性代数(19)1986,187-197)中R. C. Thompson证明了存在两个n × n酉矩阵U和V,使得$$ e^{i X}e^{i Y}=e^{i (UXU^*+VBV^*)}. $$在本文中,我们考虑将这一结果推广到紧算子以及可嵌入II $_1$因子中的算子.
英文摘要:
Let X and Y be two nxn Hermitian matrices. In the article "Proof of a conjectured exponential formula" (Linear and Multilinear Algebra (19) 1986, 187-197) R. C. Thompson proved that there exist two nxn unitary matrices U and V such that $$ e^{i X}e^{i Y}=e^{i (UXU^*+VBV^*)}. $$ In this note we consider extensions of this result to compact operators as well as to operators in an embeddable II$_1$ factor.
