On six-dimensional $G_1$-submanifolds of Cayley algebra

Se la varietà base, $N$ , di una submersione quasi-Hermitiana, $f : M \to N$ , è una $G_{1}$ -varietà e le fibre sono subvarietà superminimali, allora lo spazio totale, $M$ , è $G_{1}$ . Se la varietà base, $N$ , è Hermitiana e le fibre sono subvarietà bidimensionali e superminimali, allora lo spazio totale, $M$ , è Hermitiano.
