We extend the classical rigidity results for K -theory to the equivariant setting of linear algebraic group actions. These results concern rigidity for rational points, field extensions, and Hensel local rings. To cite this article: S. Yagunov, P.A. Østvær, C. R. Acad. Sci. Paris, Ser. I 347 (2009).
