Diffeomorphisms conformal on distributions

Kamil Niedziałomski (2009)

Annales Polonici Mathematici

Let f:M → N be a local diffeomorphism between Riemannian manifolds. We define the eigenvalues of f to be the eigenvalues of the self-adjoint, positive definite operator df*df:TM → TM, where df* denotes the operator adjoint to df. We show that if f is conformal on a distribution D, then d i m V λ 2 d i m D - d i m M , where V λ denotes the eigenspace corresponding to the coefficient of conformality λ of f. Moreover, if f has distinct eigenvalues, then there is locally a distribution D such that f is conformal on D if and only...

Distributions involutives singulières

Dominique Cerveau (1979)

Annales de l'institut Fourier

On étudie les distributions involutives, i.e. les modules D de champs de vecteurs stables par le crochet de Lie, au voisinage d’un point 0 singulier. Après s’être ramené au cas purement singulier, c’est-à-dire où tous les éléments de D s’annulent en 0, des hypothèses génériques portant sur la partie linéaire de D nous permettent d’obtenir la linéarisation.
