Globally generated implies nef For globally generated line bundles it is quite clear to see that they are nef: Let $L$ be globally generated, then the global sections in $H^0(X,L)$ define a morphism $\Phi \colon X \to...
Since it's a line bundle, that implies it's nef.

Nef
Nef是一种质量约为27-35千道尔顿的较小的豆蔻酰化的蛋白质,由灵长类慢病毒编码。其名称中的Nef是英文全称Negative Regulatory Factor的简写,意即负调节因子。 而HIV-1所表达的Nef降低了激活CD4+淋巴细胞的阈值,不过这仍不足以在外源性刺激不足的情况下使得受感染细胞进入活化状态。
Nef通过劫持细胞通信,方便自身的生存与复制。通过减少CD4受体和,Nef产生了较微弱的免疫应答,方便其复制,并且产生了一批易受其影响的细胞,而使得病毒能够进一步地感染。

Definition of being nef and big On a compact Kähler manifold $M$, given a real $(1,1)$ form $\alpha$ we say that it is nef if it is in the closure of the Kähler cone. Moreover, if $\int_{M} \alpha^n > 0$ we say that i...
The volume form is given by $\omega^n/n!$, where $\omega$ is the Kähler form.

Example of nef and big, not ample What would be a common, simple example of a nef and big divisor that is not ample? Are there any common, less simple examples? Are there any common strategies for finding examples?
If $A$ is an ample divisor on $Y$, then $f^*A$ is nef and big but not ample. But in general a nef and big divisor need not be semi-ample.

Rigid and nef implies numerically trivial If $X$ is a smooth projective variety and $L$ is an effective divisor that is both nef and rigid ($h^0(nD)=1$ for all $n\geq 0$), is $L$ numerically trivial?
in these 9 points we get a smooth surface $X$ in which the proper transform $\tilde{C}$ of $C$ is an irreducible curve with $\tilde{C}^2=0$, hence it nef

Nef的功能有哪些
Nef在病毒生命周期中较早得到表达,可以确保T细胞的激活以及持续感染状态的创建,而这两点则是HIV病毒感染的基本特征。病毒所表达的Nef大大减少了受感染细胞内部的变化,蛋白质在细胞表面的表达的调节、细胞骨架的重塑、信号通信等都受之影响。 而HIV-1所表达的Nef降低了激活CD4+淋巴细胞的阈值,不过这仍不足以在外源性刺激不足的情况下使得受感染细胞进入活化状态。Nef通过劫持细胞通信,方便自身的生存与复制。通过减少CD4受体和,Nef产生了较微弱的免疫应答,方便其复制,并且产生了一批易受其影响的细胞,而使得病毒能够进一步地感染。
