Descent for nonarchimedean analytic spaces

Brian Conrad and Michael Temkin

Vol. 3 (2021), No. 4, 689–748

We study two types of descent in the category of Berkovich analytic spaces: flat descent and descent with respect to an extension of the ground field. Quite surprisingly, the deepest results in this direction seem to be of the second type, including the descent of properties of being a good analytic space and being a morphism without boundary.
