We construct spaces of 1-dimensional supersymmetric Euclidean field theories and show that they represent real or complex K-theory. A noteworthy feature of our bordism category is that the identity bordism of a point is connected to intervals of positive length.

超对称欧几里得场论和 K 理论

我们构造一维超对称欧几里得场论的空间，并证明它们代表实数或复数 K 理论。我们的 bordism 类别的一个值得注意的特征是一个点的恒等 bordism 与正长度的区间相连。
