Let be a smooth complex projective variety equipped with an action of a linear algebraic group over . Let be a reduced effective divisor on that is invariant under the –action on . Let be the canonical section of vanishing along . Given a positive integer , consider the stack of -th roots of together with the natural morphism . Under the assumption that has no non-trivial characters, we show that the –action on naturally lifts to a –action on such that become –equivariant, and the tautological invertible sheaf on admits a linearization of this –action. Finally, we define the notions of –equivariant logarithmic connections on and –equivariant parabolic connections on with rational parabolic weights along , and establish an equivalence between the category of –equivariant logarithmic connections on and the category of –equivariant parabolic connections on with rational parabolic weights along .
