Variational principles provide a powerful and unifying framework to derive the governing equations of systems by optimising an action functional. Traditionally applied in classical mechanics via ...

T. H. R. Skyrme's variation principle for the one-nucleon propagator is cast into a new form which is essentially a functional Fourier transform of the original. Publisher Information The Royal ...
