%0 Journal Article %T Swiss-Cheese operad and Drinfeld center %A Najib Idrissi %J Mathematics %D 2015 %I arXiv %X We build a model in groupoids for the Swiss-Cheese operad, based on parenthesized permutations and braids, and we relate algebras over this model to the classical description of algebras over the homology of the Swiss-Cheese operad. We extend our model to a rational model for the Swiss-Cheese operad, and we compare it to the model that we would get if the operad Swiss-Cheese were formal. %U http://arxiv.org/abs/1507.06844v2
