Tóm tắt:An automorphism of the affine n-space is said to be wild if it does not decompose into affine automorphisms and elementary automorphisms. It is a difficult problem to decide whether a given automorphism is wild. In this talk, we discuss a similar problem for automorphisms of the affine cone of a Segre variety.
