Via He's semi-inverse method, a variational principle is established for coupled nonlinear Schrödinger equations with variable coefficients and high nonlinearity. The result obtained includes the ones known from the open literature as special cases.
## Abstract Rayleigh–Schrödinger perturbation theory for many‐electron systems has been rederived by an extension of Löwin's partitioning method in which excited configurations are further partitioned by their orders (two equivalent definitions of the __order__ of a configuration are given). The re
