Resumen de On Galois group of factorized covers of curves

Ángel Carocca, Martha Romero Rojas

• Let Y→ ψ X→ φ P 1 Y→ψX→φP1 be a sequence of covers of compact Riemann surfaces. In this work we study and completely characterize the Galois group G(φ∘ψ) of φ∘ψ under the following properties: φ is a simple cover of degree m and ψ is a Galois unramified cover of degree n with abelian Galois group of type (n1,n2,…,ns)
