Abstract

In this work, we study the decomposability property of branched coverings of degree d odd, over the projective plane, where the covering surface has Euler characteristic <= 0. The latter condition is equivalent to say that the defect of the covering is greater than d. We show that, given a datum D = [D-1, ... , D-s] with an even defect greater than d, it is realizable by an indecomposable branched covering over the projective plane. The case when d is even is known. (AU)
