Injective arrow latex
WebbInjectives. Definition 12.27.1. Let be an abelian category. An object is called injective if for every injection and every morphism there exists a morphism making the following diagram commute. Here is the obligatory characterization of injective objects. Lemma 12.27.2. Let be an abelian category. Let be an object of . WebbThe construction above defines a covariant functor from the category of -modules to the category of arrows of -modules such that for every module the output is an injective map of into an injective -module . Proof. Follows from the above. In particular, for any map of -modules there is an associated morphism making the following diagram commute:

WebbThis means, for categories of where is a reasonable notion of ‘free object generated by one element’, the underlying map of a monomorphism must be injective. Sufficient conditions. Similarly, if the underlying set functor reflects limits, then every arrow which has an injective underlying map must already be monic. didn\\u0027t 00Webb29 nov. 2024 · Latex各种箭号符号，以及在箭头上方添加字母等符号的方法 最近写博客频繁用到箭号，latex支持多种箭号，内容很丰富。 还有就是在箭号上方加上字符的方法，这里做一下 总结 字符 含义 \uparrow ↑\uparrow↑ \downarrow ↓\downarrow↓ \Uparrow ⇑\Uparrow⇑ \Downarrow ⇓\Downarrow⇓ \up... didn\\u0027t 06http://www.latex-pfeile.de/ didn't do nothing dojaWebbThe LaTeX package witharrows provides environments {WithArrows}and {DispWithArrows} similar to the environments {aligned}and {align}of amsmath but with the possibility to draw arrows on the right side of the alignment.
