Es wird ein linearer Komplex von \(k\)-dimensionalen Unterräumen definiert und untersucht. Sei \(H\) ein linearer Raum mit \(H\cong Hom(U\quad W)\cong U^*\otimes W\), wobei \(U, W\) lineare Räume mit \(\dim U=k+1\), \(\dim W=n-k\), \(\dim H=(k+1)(n-k)\) sind, dann sagen wir, daß der Raum \(H\) eine Grassmannsche Struktur hat. Der lineare Komplex wird über diese Grassmannsche Struktur definiert und untersucht (Grassmannsche Koordinaten, Grassmannsche Mannigfaltigkeiten usw. [siehe z. B. \textit{W. V. D. Hodge} und \textit{D. Pedoe}, Methods of algebraic geometry, 1. Aufl. 1952 (Zbl 0048.14502), 2.,unveränderte Aufl. 1968 (Zbl 0157.27501)]). Wir können diese Problematik als eine Verallgemeinerung des Begriffs des linearen Strahlenkomplexes auffassen.
