En-ring

In mathematics, an \mathcal{E}_n-algebra in a symmetric monoidal infinity category C consists of the following data:

for any disjoint open disks U_j contained in some open disk V

subject to the requirements that the multiplication maps are compatible with composition, and that \mu is an equivalence if m=1. An equivalent definition is that A is an algebra in C over the little n-disks operad.
