摘要：

Recently the perturbation theory for nonlinear systems was studied in detail by Leschke et al. using operator methods. We study and generalize their results in the functional integral formalism. Methods introduced in our previous work are generalized to include, in particular, normal and antinormal orderings of noncommuting operators. © 1979 The American Physical Society.
