Two-dimensional nonisotropic surfaces with flat normal connection and a nondegenerate Grassmann image of constant curvature in the Minkowski space

UDC 514.764 We find possible values of  curvature of the Grassmann manifold along the  planes tangential to the Grassmann image of a two-dimensional nonisotropic surface with flat normal connection in the four-dimensional Minkowski space. It is shown that if th...
