【 摘 要 】

We consider the theory of twisted symmetries of differential equations, in particular lambda and mu-symmetries, and discuss their geometrical content. We focus on their interpretation in terms of gauge transformations on the one hand, and of coverings on the other one. (C) 2020 Elsevier B.V. All rights reserved.
