DOI: 10.1016/j.jalgebra.2019.05.027

Abstract: Abstract We study a two-dimensional family of affine surfaces which are counter-examples to the Cancellation Problem. We describe the Makar-Limanov invariant of these surfaces, determine their isomorphism classes and characterize the automorphisms of these surfaces. read more here.
