Affine geometry and Lagrangian-Legendrian singularities

Abstract

Given a Lagrangian submanifold L of the standard symplectic space, one can define uniquely a center-chord and a special improper affine spheres whose Lagrangian singularity set contains L. We shall classify the simple stable Lagrangian and Legendrian singularities that appear in this context. (AU)
