Let M be a connected oriented surface and let Gc 2 be the Grassmannian of oriented 2-planes in Euclidean (2 + c)-space, E2+c. Smooth maps t: M → Gc 2 are studied to determine whether or not they are ...
Abstract The notion of pointwise 1-type Gauss map was derived from the ordinary finite type Gauss map and it gives an interesting geometric properties on surfaces of 3-dimensional Euclidean space. In ...
