Let $f:X\to Y$ be an integral surjection. A scheme has the weak Cartan--Artin property when the associated fiber constructions at sequences of geometric points have the weak acycli…

Let $f:X\to Y$ be an integral surjection. A scheme is acyclic with respect to a Grothendieck topology if its higher cohomology with coefficients in every abelian sheaf for that top…
