Remarks on numerically positive line bundles on normal surfaces.
Locally finite iterative higher derivations on k[x,y]
We give a new proof of Miyanishi's theorem on the classification of the additive group scheme actions on the affine plane.
An algorithm for computing the kernel of a locally finite higher derivation up to a certain degree
This paper gives an algorithm for computing the kernel of a locally finite higher derivation on the polynomial ring k[x₁,..., xₙ] up to a given bound.
