论文摘要
我们计算每个紧凑型，简单连接的拓扑4 manifold的拓扑映射类组。以前仅在封闭情况下才知道。如果4个manifold平滑，我们将推断出稳定的平滑映射类组的类似描述，从而扩展了Saeki的工作。
We compute the topological mapping class group of every compact, simply connected, topological 4-manifold. This was previously only known in the closed case. If the 4-manifold is smooth, we deduce an analogous description of the stable smooth mapping class group, extending work of Saeki.
