Existence of the Minimum of the Functional , in the Space ,. Generalized Solutionsd of Chap. 9 we have noted that Theorem 9.2 has a conditional character since it assumes either the existence of the solution . ∈ . of the given equation or the existence of the element . ∈ . minimizing the functional . on ., while the existence of such an element . is a priori guaranteed in neither the first nor the second case.

Theorem on the Minimum of a Quadratic Functional and its Consequenceson (9.3) on .. We have shown (cf. Theorem 8.6, or Remark 8.5 and Exs. 8.8 and 8.10) that . is dense in the Hilbert space .(.) and that the operator -Δ is symmetric and positive on .. We have mentioned that it will be shown later that this operator is even positive definite.

Introductiont one of the youngest. The reason lies in the fact that through differential equations the majority of phenomena studied in physics may be described, and — consequently — also of phenomena arising in fields related to physics as well as in fields which have broken away from physics as independent sc

Inner Product of Functions. Norm, Metricn connected set in the Euclidean space .. Only bounded domains with the so-called . will be considered in this book. The definition of this concept is rather complicated and would cause the reader unnecessary difficulties at this opening stage. Therefore, it is left over to Chap. 28. Here we note on
