Resumen de On the topology of singularities of the set of supporting hyperplanes of a smooth submanifold in an affine space

V. D. Sedykh

• Many new universal relations are obtained between the Euler numbers of manifolds of singular supporting hyperplanes of an arbitrary generic smooth closed -dimensional submanifold in where or . These relations are applied to Barner-convex curves in an odd-dimensional space . A universal (nontrivial) linear relation is established between the numbers of singular supporting hyperplanes of various types but of the same total multiplicity of tangency with a given generic smooth closed connected Barner-convex curve in . The coefficients of this relation are defined by Catalan numbers.
