Lagrange transformations and duality for corner and flag singularities

  • Inna Scherbak
  • Aviva Szpirglas


Singularities on a space with a fixed collection of subspaces are studied. Homological objects for the singularities are constructed. A Lagrange transformation of the singularities is defined. It is shown that on the set of the isolated singularities, the Lagrange, transformation is an involution realizing the duality of corresponding homological objects.
