• Twisted form
• Derivation
• Centroid
• Etale descent
• Multiloop algebra

We give an explicit description of the Lie algebra of derivations for a class of infinite dimensional algebras which are given by ,tale descent. The algebras under consideration are twisted forms of central algebras over rings, and include the multiloop algebras that appear in the construction of extended affine Lie algebras.
