Algebra gl(λ) inside the algebra of differential operators on the real line

Hichem Gargoubi

The Lie algebra gl(λ) with λ\in \mathbb C, introduced by B.L.Feigin, can be embedded into the Lie algebra of differential operators on the real line. We give an explicit formula of…

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…
