Multi-centered dilatations and congruent isomorphisms

Arnaud Mayeux

Published 2023-03-14, updated 2023-04-08Version 2

We introduce a multi-centered formalism in the context of dilatations of schemes and algebraic spaces. In particular, this provides new results on the behavior of [MRR20] dilatations. Furthermore, we use our new formalism to deduce some refined congruent isomorphisms.
