Abstract

In most of the examples in Chapter 3, we examined a real-valued function F defined on a domain of functions D. We obtained for F an integral condition in the form I(y; v) = 0, ∀ v in an auxiliary domain D0, which is sufficient to guarantee that each yD that satisfies it must minimize F on D.
