| Popis: | We establish Tannaka duality for noetherian algebraic stacks with affine stabilizer groups. Our main application is the existence of Hom-stacks in great generality. Comment: 41 pages; various improvements; quasi-separatedness of Hom-stack (Appendix B); more counter-examples (Section 10); former Appendix B is now in arXiv:1606.08517; some corrections and improvements |
