nLab Swiss cheese operad


The Swiss cheese operad is an analogue of the little disks operad, where disks are replaced by half-disks, which contain both ordinary disks in their interior, as well as half-disks positioned at the flat boundary.

This structure can be organized into an operad in the category of modules over the little disks operad.

The Swiss cheese operad over rationals is not formal, unlike the little disks operad.
