The topological holonomy group and the complexity of horizontality

Naoya Ando, Anri Yonezaki

Based on [1], we study the complexity of horizontality in each twistor space $E^_{ε}$ associated with an oriented vector bundle $E$ of rank $4$ with a positive-defin…

Nilpotent structures of oriented neutral vector bundles

Naoya Ando

In this paper, we study nilpotent structures of an oriented vector bundle $E$ of rank $4 n$ with a neutral metric $h$ and an $h$ -connection $\nabla$ . We define $H$ -nilpotent structu…

Horizontality with infinite complexity in the twistor spaces on tori

Naoya Ando, Anri Yonezaki

We study the complexity of horizontality in the twistor space $E^$ associated with an oriented vector bundle $E$ of rank $4$ with a positive-definite metric over a torus. If t…
