We essentially determine the saturated 2‐fusion systems of J‐component type in which the centralizer of some fully centralized involution of maximal 2‐rank contains a component that is the 2‐fusion system of an alternating group $A_n$ for some $n⩾8$.

具有交替J分量的融合系统

我们实质上确定了J分量类型的饱和2融合系统，其中某些最大2秩的完全集中对合的扶正器包含一个分量，该分量是交替组的2融合系统 ${\mathrm{一种}}_{ñ}$ 对于一些 $ñ⩾8$。
