Verf. gibt die allgemeinste Form derjenigen Tensoren an, deren Komponenten sämtlich absolute Konstanten sind. Sind \(p\) Indices kontravariant und \(q\) Indices kovariant, so läßt sich ein solcher Tensor im Falle \(p=q\) mittels der \(\delta_k^i\) (\(= 0\) für \(i\neq k\), \(= 1\) für \(i = k\)) ausdrücken; im Falle \(p\neq q\) sind alle Komponenten gleich 0.
