Abstract
Let be a reduced effective strict normal crossing divisor on a smooth complex variety , and let be an associated root stack over . Suppose that admits an anti-holomorphic involution (real structure) that keeps invariant. We show that the root stack naturally admits a real structure compatible with . We also establish an equivalence of categories between the category of real logarithmic connections on this root stack and the category of real parabolic connections on .
