Explicit Description of the Zassenhaus Formula

Published 15 Feb 2017 in math-ph, hep-th, math.MP, and quant-ph | (1702.04681v2)

Abstract: We explicitly describe an expansion of $e^{A+B}$ as an infinite sum of the products of $B$ multiplied by the exponential function of $A$. This is the explicit description of the Zassenhaus formula. We also express the Baker-Campbell-Hausdorff formula in a different manner.
