    Séminaire GSD "Codimension one holomorphic distributions on the projective three-space"

    Résumé : We study codimension one holomorphic distributions on the projective three-space, analyzing the properties of their singular schemes and tangent sheaves. In particular, we provide a classification of codimension one distributions of degree at most 2 with locally free tangent sheaves, and show that codimension one distributions of arbitrary degree with only isolated singularities have stable tangent sheaves.
    Finally, we prove that every rational foliation has stable tangent sheaf, while the tangent sheaf of a logarithmic foliation of degree at most 2 either splits as a sum of line bundles, or it is semistable. Joint work with Mauricio Correa and Omegar Calvo-Andrade.
