我们研究了族中的测试理想和F-奇点的行为。特别是,我们得到一般(和非一般)的测试理想和非F-纯理想的限制定理。此外,我们研究了某些典型的线性系统(引起Frobenius)与伴随线丛,在家庭的整体行为。作为结果,我们得到了一些积极的结果,推进的一些伴随线丛和某些子层。
We study the behavior of test ideals and F-singularities in families. In particular, we obtain generic (and non-generic) restriction theorems for test ideals and non-F-pure ideals. Additionally, we study the global behavior of certain canonical linear systems (induced by Frobenius) associated to adjoint line bundles, in families. As a consequence, we obtain some positivity results for pushforwards of some adjoint line bundles and for certain subsheaves of these.
