This can be viewed as infinity-categorical generalization of the work of Joyal-Street and Nori. We then apply it to the stable infinity-category of mixed motives equipped with the realization functor of a mixed Weil cohomology and obtain a derived motivic Galois group whose representation category has a universality, and which represents the automorphism group of the realization functor. Also, we present basic properties of derived affine group schemes in Appendix.", "revisions": [ { "version": "v3", "updated": "2012-08-17T14:19:24.000Z" } ], "analyses": { "keywords": [ "derived algebraic geometry", "derived affine group scheme", "symmetric monoidal infinity-category", "realization functor", "representation category" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1112.1761I" } } }
