On automorphisms of Danielewski surfaces

Anthony J. Crachiola

We develop techniques for computing the AK invariant of a domain with arbitrary characteristic. We use these techniques to describe for any field $K$ the automorphism group of $K[X…

Return of $x + x^{2} y + z^{2} + t^{3} = 0$

Anthony J. Crachiola

We develop techniques for computing the AK invariant of domains with arbitrary characteristic. As an example, we show that for any field $K$ the ring $K[X,Y,Z,T] / (X + X^2 Y + Z^2…

On the rigidity of small domains

Anthony J. Crachiola, Leonid Makar-Limanov

Let $K$ be an algebraically closed field of arbitrary characteristic. Let $A$ be an affine domain over $K$ with transcendence degree 1 which is not isomorphic to $K [x]$ , and let $B…
