The Euler characteristic of a generic wave front in a 3‐manifold
Get PDFWe give a relation between Euler characteristics of a generic closed Legendrian surface and its wavefront
The Euler number of a topologically stable singular surface in a 3‐manifold
Get PDFA formula for the Euler number of a generic singular surface in a 3-manifold is given. This formula not only unifies the previous results but also allows some new applications
