User:TakuyaMurata/Simplicial commutative ring

In algebra, a simplicial commutative ring is a commutative monoid in the category of simplicial abelian groups. If A is a simplicial commutative ring, then it is immediate that $$\pi_0 A$$ is a commutative ring and $$\pi_i A$$ are modules over that ring.

A topology-counterpart of this notion is a commutative ring spectrum.
