Query: Mayer-Vietoris squares in algebraic geometry   We consider various notions of Mayer--Vietoris squares in algebraic geometry.
We use these to generalize a number of gluing and pushout results of
Moret-Bailly, Ferrand--Raynaud, Joyet and Bhatt. An important intermediate step
is Gabber's rigidity theorem for henselian pairs, which our methods give a new
proof of.
