Query: On the Geometry of Twisted Symmetries: Gauging and Coverings   We consider the theory of \emph{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.
