| Résume | We will discuss a few questions of cohomological nature related with current Lie algebras, i.e. algebras formed as the tensor product of a Lie algebra and an associative commutative algebra. We will describe deformations of a certain class of such Lie algebras (generalizing an old result of Lecomte and Roger), give applications to the question of finitness of a number of cohomologically nontrivial modules of a fixed finite dimension, and to some questions about varieties of Lie algebras. |
