Query: Topological rigidification of schemes   We show that any of a large class of schemes receives a universal
homeomorphism from a reduced scheme that in turn receives no nontrivial
universal homeomorphism from any other reduced scheme. This construction serves
as a categorical input for the formal inversion of universal homeomorphisms;
the result is an infinity-category that embeds as a full subcategory of the h
infinity-topos of Voevodsky.
