Abstract

Is every algebraic action of a reductive algebraic group G on affine space Cⁿ equivalent to a linear action? The “normal linearization theorem” proved below implies that, if each closed orbit of G is a fixed point, then Cⁿ is G-equivariantly isomorphic to (Cⁿ)^G X C^m for some linear action of G on Cm.
