Abstract
In the first section we recall some basic notions on Lie algebras. In a second time we study the algebraic variety of complex -dimensional Lie algebras. We present different notions of deformations : Gerstenhaber deformations, pertubations, valued deformations and we use these tools to study some properties of this variety. Finaly we introduce the concept of rigidity and we present some results on the class of rigid Lie algebras.
