More generally, it is concerned with stationary values of functionals, which occur when arbitrarily small changes in a function results in a vanishing variation of the functional, where variation is defined as the linear part of the resulting change of the functional.
These occur when arbitrarily small changes in a function results in a vanishing of the variation of the functional. More generally, it is concerned with stationary values of functionals.
