Singularities of affine equidistants: extrinsic geometry of surfaces in 4-space

W. Domitrz, S. Janeczko, P. de M. Rios +1

For a generic embedding of a smooth closed surface $M$ into ${\mathbb{R}}^4$, the subset of ${\mathbb{R}}^4$ which is the affine $\lambda$-equidistant of $M$ appears as the discriminant set of…
