Branched covers of the sphere and the prime-degree conjecture
Maria Antonietta Pascali, Carlo Petronio
To a branched cover between closed, connected and orientable surfaces one associates a "branch datum", which consists of the two surfaces, the total degree d, and the partitions of…

Surface branched covers and geometric 2-orbifolds
Maria Antonietta Pascali, Carlo Petronio
For a branched cover between two closed orientable surfaces, the Riemann-Hurwitz formula relates the Euler characteristics of the surfaces, the total degree of the cover, and the t…
