Decomposability of minimal defect branched coverings over the projective plane
Natalia A. Viana Bedoya, Daciberg Lima Gonçalves
In this paper we characterize primitive branched coverings with minimal defect over the projective plane with respect to the properties decomposable and indecomposable. This minima…
