Industrial Marketing GenerationsThe Laplace operator possesses a remarkable feature of monotonicity permitting us to study the solvability of elliptic problems. The statement is given in Theorem 25.1.

Classical Variational Method,In this chapter and throughout the book, we shall consider boundary problems of the form. Functions . : ?. x ? → ? are supposed to satisfy a so-called Carathéodory condition, i.e., to be continuous with respect to . for almost all x ∈ ?. and measurable in x for all . ∈ ?.

Variational Methods for Eigenvalue Problems,Up to now we have studied problems of a coercive type. Investigation of noncoercive problems requires other methods. One of the ways is the reduction of an original elliptic problem to a new one with a free parameter (eigenvalue) and the investigation of this new problem, for example, by the method of a conditional extremum.
