Zusammenfassung

In diesem Kapitel studieren wir, für ein Kompaktum \(\Omega\subset \mathbb{R}^d , d\geq1,\) die Approximation von stetigen Funktionen aus dem linearen Raum.

$$\mathscr{C}(\Omega ) = \{ u:\Omega \to {\mathbb{R| }}u\,{\rm{stetig}}\} $$

bezüglich der Maximumnorm

$$\parallel u{\parallel _\infty } = \mathop {\max }\limits_{x \in \Omega } |u(x)|\,\,\,\,\,f\ddot{u} r\,u \in \mathscr{C}(\Omega ).$$
