Exponential Formulas, Normal Ordering and the Weyl-Heisenberg Algebra
We consider a class of exponentials in the Weyl-Heisenberg algebra with exponents of type at most linear in coordinates and arbitrary functions of momenta. They are expressed in terms of normal ordering, where coordinates stand to the left of momenta. Exponents appearing in normal ordered form satis...
