【 摘 要 】

In this paper we introduce the notion of global equivariant. hom-Lie algebra. This is a Lie algebra-like structure associated with twisted derivations. We prove several results on the structure of modules of twisted derivations and how they form global equivariant horn-Lie algebras. Particular emphasis is put on examples and results in arithmetic geometry. (C) 2017 Elsevier Inc. All rights reserved.
