Double coverings of hyperelliptic real algebraic curves
The authors consider (branched) coverings of degree two between closed Riemann surfaces, say \(\pi:X \to Y\), where \(X\) is assumed to be hyperelliptic and both \(X\) and \(Y\) admit an anticonformal involution. A complete description in algebraic terms is given for all possible such branched coverings.
