In Physics, there exists an important class of operators of the form $e^{i A}$ (see equation ($14$) in this article). It is often of interest to calculate the trace $Tr[B e^{i A}]$ (such as equation ($18$) ). I want to know whether there is some standard way(s) to approach this problem in Mathematics?
