It is shown that, if the hamiltonian H has a normal constant of motion A or n group G = {g) o f such wnstants, and if the subspace AI is stable under A or the group G = {g), then the vxiational solutions 6 show exactly the same type of symmetry properties as the exact eigenfunctions.

New, gauge-independent, second-order Lagrangian for the motion of classical, charged test particles is proposed. It differs from the standard, gauge-dependent, first-order Lagrangian by boundary terms only. A new method of deriving equations of motion from field equations is developed. When applied

## Abstract A general variational principle for transition and density matrices is proposed. The principle is closely related to Rowe's variational treatment of the equations‐of‐motion method. It permits the simultaneous construction of coupled approximations for two eigenstates, and it is a straig
