1272. Michael Lieberman, Jiří Rosický, Sebastien Vasey Universal abstract elementary classes and locally multipresentable E-mail: Submission date: 27 July 2017 Abstract: We exhibit an equivalence between the model-theoretic framework of universal classes and the category-theoretic framework of locally multipresentable categories. We similarly give an equivalence between abstract elementary classes (AECs) admitting intersections and locally polypresentable categories. We use these results to shed light on Shelah's presentation theorem for AECs. Mathematics Subject Classification: 03C48 (Primary), 18C35, 03C52, 03C55, 03C75 (Secondary) Keywords and phrases: |
