Abstract

We study 3-manifolds in \({\mathbb {R}}^5\) with corank 1 singularities. At the singular point we define the curvature locus using the first and second fundamental forms, which contains all the local second order geometrical information about the manifold. Also, we relate the geometry of these objects to the geometry of regular 3-manifolds in \({\mathbb {R}}^6\).
