摘要：Descent theory comes from the algebraic geometry, it has been widely studied over the last decade, especially its applications in Lie algebras, more precisely, affine Kac-Moody algebras and extended affine Lie algebras (EALAs).  The idea behind is that one can view Lie algebras as twisted forms and then (non-abelian) cohomology comes into picture. In this talk, we will first introduce the ideas and methods that will be used, and the recent progress in this direction, then we give our results about the descent considerations (in both faithfully flat ́etale and Galois cases) for the derivation algebras of certain Lie algebras relarted to EALAs. This is a joint work with Arturo Pianzola.
