Definition

A deck transformation or cover automorphism is an automorphism of a cover.

i.e. if p:E→Xp:E\to X is a cover then a cover automorphism f∈deck(p)={f|f∈Aut(E),p∘f=p}⊆Aut(E)f\in deck(p)=\{f|f\in Aut(E), p\circ f=p\}\subseteq Aut(E) is an automorphism of EE such that pp is invariant under composition with ff.
