Abstract
Surfaces which are both affine and Euclidean minimal are called Thomsen surfaces. In ℝ3, these surfaces have been completely classified byBarthel, Volkmer andHaubitz. A similar problem, in the Lorentzian 3-space was solved byMagid. In the present paper, we study Thomsen surfaces in ℝ4 and show that these surfaces are affine equivalent to the complex paraboloid.
