Permutation Algebraic Geometry: Presentations, Algebraic Subspaces, Covering Groupoids, Cohomology, Topoi, and Fibres

  We construct permutation algebraic geometry from actions on presentations rather than automorphisms of one fixed space. In the affine polynomial sector, a slot permutation gives a linear operator \(T_w\) that is generally nonmultiplicative. For an ideal \(I\subseteq S\), the closure\[I^{[w]}=\langle T_w(I)\rangle\]defines a new closed subscheme,
