Building upon our recent operadic approach to this subject, we show that the category of such theories carries a canonical model structure and explain the important conceptual and also practical consequences of this result. As a concrete application we provide a derived version of Fredenhagen's universal algebra construction, which is relevant e.g. for the BRST/BV formalism. We further develop a homotopy theoretical generalization of algebraic quantum field theory with a particular focus on the homotopy-coherent Einstein causality axiom. We provide examples of such homotopy-coherent theories via (1) smooth normalized cochain algebras on $\\infty$-stacks, and (2) fiber-wise groupoid cohomology of a category fibered in groupoids with coefficients in a strict quantum field theory.", "revisions": [ { "version": "v1", "updated": "2018-05-22T18:00:20.000Z" } ], "analyses": { "subjects": [ "81Txx", "18D50", "18G55", "55U35" ], "keywords": [ "algebraic quantum field theory", "homotopy theory", "chain complex valued algebraic quantum", "complex valued algebraic quantum field", "fredenhagens universal algebra construction" ], "note": { "typesetting": "TeX", "pages": 34, "language": "en", "license": "arXiv", "status": "editable" } } }
