Abstract
We develop methods for approximating the exponential of the sum of any number of noncommutative operators each linear in a parameter α by a product of exponentials of the individual operators to a given order in α. In particular, we implement a symbolic manipulation program which locates products with a minimal number of operators. Such expressions are associated with highly efficient field propagation techniques.
