论文摘要
我们在线性阿贝尔类别中使用通用扩展的概念来研究混合霍奇结构以及收敛和过度凝结等晶体的变化的扩展。我们获得的结果适用，例如，以证明这些类别的某些同质序列的精确性并研究$ f $ -able等晶体。
We use the notion of universal extension in a linear abelian category to study extensions of variations of mixed Hodge structure and convergent and overconvergent isocrystals. The results we obtain apply, for example, to prove the exactness of some homotopy sequences for these categories and to study $F$-able isocrystals.
