Abstract
Free algebraic actions of a connected algebraic groupG onC 3 which can be triangularized are shown to be trivial, that isC 3 is equivariantly isomorphic toGxC 3−dimG. This result follows directly from the case of the additive groupG=G a and is shown to hold for quasi-algebraic actions as well. Connections with the classification of homogeneous affine varieties are discussed.
