Derivation algebras of toric varieties
Antonio Campillo, Janusz Grabowski, Gerd Müller
Normal affine algebraic varieties in characteristic 0 are uniquely determined (up to isomorphism) by the Lie algebra of derivations of their coordinate ring. This is not true witho…

Analytic varieties versus integral varieties of Lie algebras of vector fields
Herwig Hauser, Gerd Muller
We associate to any germ of an analytic variety a Lie algebra of tangent vector fields, the {\it tangent algebra}. Conversely, to any Lie algebra of vector fields an analytic germ…
