Affine focal sets of codimension $2$ submanifolds contained in hyper surfaces

Marcos Craizer, Marcelo J. Saia, Luis F. Sánchez

In this paper we study the affine focal set, which is the bifurcation set of the affine distance to submanifolds $N^n$ contained in hypersurfaces $M^{n+1}$ of the $(n+2)$-space. We…
