Horizontal Ga-actions on affine T-varieties of complexity one

  • Kevin Langlois Heinrich Heine University, Du ̈sseldorf, Germany

Abstract

We classify the G a -actions on normal affine varieties defined over a field that are hori-
zontal with respect to a torus action of complexity one. This generalizes previous versions that were
available for perfect ground fields (cf. [7, 12, 11]).
