izing Eq. (1.1) is analyzed in this chapter devoted to the variational calculus. We shall consider rst the standard problem, where ˚ 1 and ˚ 2 are xed on the boundaries. This corresponds to the case in which the surface contribution are very large with respect to the bulk contribution in Eq. (1.1): 1
