我们研究微分分级代数 (DGA),其同源性是 n 阶生成元上交换环 R 上的外代数,以及这些 DGA 上的某些类型的微分模。我们通过 R=ℤ 或 R=픽p 和 n⩾−1 获得完整的分类。这些例子出乎意料地有趣。
We study differential graded algebras (DGAs) whose homology is an exterior algebra over a commutative ring R on a generator of degree n, and also certain types of differential modules over these DGAs. We obtain a complete classification with R=ℤ or R=픽p and n⩾−1. The examples are unexpectedly interesting.
