Sommario/riassunto |

"We develop a universal framework to study smooth higher orbifolds on the one hand and higher Deligne-Mumford stacks (as well as their derived and spectral variants) on the other, and use this framework to obtain a completely categorical description of which stacks arise as the functor of points of such objects. We choose to model higher orbifolds and Deligne-Mumford stacks as infinity-topoi equipped with a structure sheaf, thus naturally generalizing the work of Lurie (2004), but our approach applies not only to different settings of algebraic geometry such as classical algebraic geometry, derived algebraic geometry, and the algebraic geometry of commutative ring spectra as in Lurie (2004), but also to differential topology, complex geometry, the theory of supermanifolds, derived manifolds etc., where it produces a theory of higher generalized orbifolds appropriate for these settings. This universal framework yields new insights into the general theory of Deligne-Mumford stacks and orbifolds, including a representability criterion which gives a categorical characterization of such generalized |

Deligne-Mumford stacks. This specializes to a new categorical description of classical Deligne-Mumford stacks, a result sketched in Carchedi (2019), which extends to derived and spectral Deligne-Mumford stacks as well"-- |

Sommario/riassunto |

Honor Frost has written a travel book with this difference: her journeys have extended below the surface of the sea. Her accounts of these regions can be compared with the writings of early travellers who, unhampered by overspecialization, recorded a variety of observations on completely unknown places. In setting down her direct experience she has thrown new light on the much discussed submect of underwater archaeology.This book contains 22 colour and 28 monochrome photographs by well known divers, also 52 plans and drawings by the author illustrating her arguments. It is addressed to travell |
