More often than not, the procedure involves the minimization of integrals containing unknown functions and their derivatives, without first deriving from these integrals equivalent (the so-called Euler-Lagrange) differential equations.

Sonya Dal Cin,Michael P. Hall,Daniel S. Laneering, in particular, in dynamics, electromagnetism, quantum field theory, and optimization. We here have in mind problems in which such classical requirements as the regularity and differentiability of functions, convergence of series, and smoothness of boundary conditions cannot be maintained, but

Function Space,bstract space element—at this stage we choose to change our approach and concentrate on the particular class of abstract spaces known as function spaces. A . is an abstract space, the elements of which are functions or sets of functions defined in an appropriate domain.

Reference work Nov 20073rd editionWhereas the . lists as many as nineteen connotations of the word “space,” for the purposes of this exposition it is sufficient to consider only two, which we shall designate more specifically by the terms “physical” and “abstract” space.
