摘要翻译:
定义了向量丛态射的一种新的对称性,称为三性对称性,并计算了此类态射简并轨迹的Chern类公式。在附录中,我们展示了如何将一个八倍数代数丛规范地关联到任何秩2向量丛。

英文摘要:
We define a new symmetry for morphisms of vector bundles, called triality symmetry, and compute Chern class formulas for the degeneracy loci of such morphisms. In an appendix, we show how to canonically associate an octonion algebra bundle to any rank 2 vector bundle.
