Building upon our earlier work with M. C. Hughes, we construct many new smooth structures on closed simply connected nonspin $4$ -manifolds with positive signature. We also provide numerical and asymptotic upper bounds on the function $\lambda (\sigma )$ that was defined in our earlier work.

具有正签名的简单连接的非自旋辛 4 流形的地理。二

在我们早期与 MC Hughes 合作的基础上,我们在具有正签名的闭合简单连接非自旋 $4$- 流形上构建了许多新的平滑结构。我们还提供了我们早期工作中定义的函数 $\lambda (\sigma )$ 的 数值和渐近上限。
