Automorphism Groups of Danielewski Surfaces
Matthias Leuenberger, Andriy Regeta
In this note we study the automorphism group of a smooth Danielewski surface , where i…
(Volume) Density Property of a family of complex manifolds including the Koras-Russell Cubic
Matthias Leuenberger
We present modified versions of existing criteria for the density property and the volume density property of complex manifolds. We apply this methods to show the (volume) density…
Complete Algebraic Vector Fields on Danielewski Surfaces
Matthias Leuenberger
We give the classification of all complete algebraic vector fields on Danielewski surfaces (smooth surfaces given by ). We use the fact that for each such vector field the…
Complete algebraic vector fields on affine surfaces
Shulim Kaliman, Frank Kutzschebauch, Matthias Leuenberger
Let $\AAutH (X)$ be the subgroup of the group $\AutH (X)$ of holomorphic automorphisms of a normal affine algebraic surface generated by elements of flows associated with compl…
The algebraic density property for affine toric varieties
Frank Kutzschebauch, Matthias Leuenberger, Alvaro Liendo
In this paper we generalize the algebraic density property to not necessarily smooth affine varieties relative to some closed subvariety containing the singular locus. This propert…
Lie algebra generated by locally nilpotent derivations on Danielewski surfaces
Frank Kutzschebauch, Matthias Leuenberger
We give a full description of the Lie algebra generated by locally nilpotent derivations (short LNDs) on smooth Danielewski surfaces given by . In case $\mathrm{deg}…
