Abstract

We study the geometry of immersed surfaces in the 4-affine space, we will characterize these from singularities which appear in the contact of the surfaces with hyperplanes obtained from the height function, since these are affine invariants. Mochida, Romero-Fuster and Ruas described this problem in the Euclidean case and obtained results of the geometry of a surface. We intend to develop the affine case that has not yet been explored in the general case of codimension 2. (AU)
