On the density of strongly minimal algebraic vector fields

Abstract

Two theorems witnessing the abundance of geometrically trivial strongly minimal autonomous differential equations of arbitrary order are shown. The first one states that a generic algebraic vector field of degree d ≥ 2 on the affine space of dimension n ≥ 2 is strongly minimal and geometrically trivial. The second one states that if X 0 is the complement of a smooth hyperplane section H X of a smooth projective variety X of dimension n ≥ 2 then for d ≫ 0, the system of differential equations associated with a generic vector field on X 0 with poles of order at most d along H X is also strongly minimal and geometrically trivial.
