本文定义并研究了实纤维态射。这种态射出现在实双曲超曲面的研究中。

和其他双曲线品种。我们证明了实纤维态射与允许正定对称双线性形式的Ulrich层紧密相连。
In this paper, we define and study real fibered morphisms. Such morphisms arise in the study of real hyperbolic hypersurfaces in

and other hyperbolic varieties. We show that real fibered morphisms are intimately connected to Ulrich sheaves admitting positive definite symmetric bilinear forms.
