Abstract

Given two arbitrary vector bundles on the Fargues–Fontaine curve, we give an explicit criterion in terms of Harder–Narasimhan polygons on whether they realize a semistable vector bundle as their extensions. Our argument is largely combinatorial and builds upon the dimension analysis of certain moduli spaces of bundle maps developed in $\href{https://doi.org/10.1017/S1474748020000183}{[1]}$.

论 p$-adic 几何中向量束的某些扩展
给定法尔古斯-方丹曲线上的两个任意向量束,我们用哈尔德-纳拉西姆汉多边形给出了一个明确的判据,判定它们是否实现了作为其扩展的半稳向量束。我们的论证主要是组合性的,建立在$\href{https://doi.org/10.1017/S1474748020000183}{[1]}$中对某些束映射模空间的维度分析之上。
