理解"tangent/vectorbundle、vectorfield和section"这几个概念的关键在于把握它们之间的逻辑关系以及直观形象的理解。首先，向量丛是纤维丛的一个特殊情况，每个"纤维"都是向量空间，这定义了向量丛的基本性质。在给定流形的背景下，切丛与余切丛是特殊的向量丛，它们无需额外结构即可自然定义，但其他向量丛则...

In the case n=2, where delta-Ulrich sheaves satisfy the property that their direct image under a general finite linear projection is a semistable instanton bundle, we show that some high Veronese embedding of X admits a delta-Ulrich sheaf with a global section....

Vector Field (redirected fromTangent bundle section) Dictionary vector field [′vek·tər ‚fēld] (mathematics) The field of vectors arising from considering a system of differential equations on a differentiable manifold. A function whose range is in a vector space. ...
We point out a connection between bigness of the tangent bundle of a smooth projective variety X over and simplicity of the section rings of X as modules over their rings of differential operators. As a consequence, we see that the tangent bundle of a smooth projective toric variety or a ...
