Strongly Incompressible Curves

  • Mario Garcia-Armas (a1)

Let G be a finite group. A faithful G-variety X is called strongly incompressible if every dominant G-equivariant rationalmap of X onto another faithful G-variety Y is birational. We settle the problem of existence of strongly incompressible G-curves for any finite group G and any base field k of characteristic zero.
