摘要:

对分离的拟紧方案S上的任意阿贝尔范畴\calC satfisfying(AB 5),构造了S的平坦点上的2-群\GL(\calC)的栈.当\calC是S上分离的拟紧概型X上的拟凝聚层范畴时,我们将给出\GL(\calC)的具体描述.我们将证明\GL(\calC)在原点处的切空间\gl(\calC)具有作为Lie 2-代数的结构。

英文摘要:

For any abelian category \calC satsifying (AB5) over a separated, quasi-compact scheme S, we construct a stack of 2-groups \GL(\calC) over the flat site of S. We will give a concrete description of \GL(\calC) when \calC is the category of quasi-coherent sheaves on a separated, quasi-compact scheme X over S. We will show that the tangent space \gl(\calC) of \GL(\calC) at the origin has a structure as a Lie 2-algebra.
