In algebra, the ring of polynomial differential forms on the standard n-simplex is the differential graded algebra:[1]
![{\displaystyle \Omega _{\text{poly}}^{*}([n])=\mathbb {Q} [t_{0},...,t_{n},dt_{0},...,dt_{n}]/(\sum t_{i}-1,\sum dt_{i}).}](https://wikimedia.org/enwiki/api/rest_v1/media/math/render/svg/8561d29e88a143455f96301cf790bb56fd218cea)
Varying n, it determines the simplicial commutative dg algebra:
(each induces the map ).
![{\displaystyle u:[n]\to [m]}](https://wikimedia.org/enwiki/api/rest_v1/media/math/render/svg/a39fd8924b9cb09430e0cc1161803300fe55a2b5)
![{\displaystyle \Omega _{\text{poly}}^{*}([m])\to \Omega _{\text{poly}}^{*}([n]),t_{i}\mapsto \sum _{u(j)=i}t_{j}}](https://wikimedia.org/enwiki/api/rest_v1/media/math/render/svg/3d60e3ec6f36c3f7bdc8bec9c08cf236e21bcabe)
