Abstract
In this paper we analyze the center–focus problem of some families of piecewise planar quadratic vector fields on two zones of R2R2. The zones we consider are two unbounded sectors defined by an arbitrary angle α and a fixed vertex. We also assume that each vector field share a common weak focus singularity at the vertex of the boundary. We observe how the center variety depends on the angle α.
