%0 Journal Article %T Ringel duality and derivatives of non-additive functors %A Antoine Touz¨¦ %J Mathematics %D 2011 %I arXiv %X We prove that Ringel duality in the category of strict polynomial functors can be interpreted as derived functors of non-additive functors (in the sense of Dold and Puppe). We give applications of this fact for both theories. %U http://arxiv.org/abs/1103.4580v4
