Real Structures on Root Stacks and Parabolic Connections

Abstract

Let DD be a reduced effective strict normal crossing divisor on a smooth complex variety XX, and let XD\mathfrak{X}_D be an associated root stack over C\mathbb C. Suppose that XX admits an anti-holomorphic involution (real structure) that keeps DD invariant. We show that the root stack XD\mathfrak{X}_D naturally admits a real structure compatible with XX. 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 XX.
