nLab ring operad

In mathematics, a highly structured ring spectrum or ∞-ring is an object in homotopy theory encoding a refinement of a multiplicative structure on a cohomology theory. A commutative version of an ∞-ring is called an E-∞ ring. While originally motivated by questions of geometric topology and bundle theory, they are today most often used in stable homotopy theory.
