Dillen, F.; Mys, G.; Verstraelen, L.; Vrancken, L. The affine mean curvature vector for surfaces in \(\mathbb{R}^ 4\). (English) Zbl 0833.53011 Math. Nachr. 166, 155-165 (1994). The authors study nondegenerate affine surfaces in \(\mathbb{R}^4\) following the approach introduced by K. Nomizu and L. Vrancken [Int. J. Math. 4, No. 1, 127-165 (1993; Zbl 0810.53006)]. They find the relationship between the property that a surface has extremal area under certain variations and the property that the affine mean curvature vector vanishes.
