Projectively Invariant Cocycles of Holomorphic Vector Fields on an Open Riemann Surface

S. Bouarroudj, H. Gargoubi

Let $Σ$ be an open Riemann surface and $H o l (Σ)$ be the Lie algebra of holomorphic vector fields on $Σ.$ We fix a projective structure (i.e. a local $S L_{2} (C) -$ structure) on $Σ.$ We…

Projective and Conformal Schwarzian Derivatives and Cohomology of Lie Algebras Vector Fields Related to Differential Operators

Sofiane Bouarroudj

Let $M$ be either a projective manifold $(M, P i)$ or a pseudo-Riemannian manifold $(M, g) .$ We extend, intrinsically, the projective/conformal Schwarzian derivatives that we have int…
