Surfaces of the class VII\(_0\) admitting a vector field
The authors prove that a compact complex surface of class \(\text{VII}_0\) with \(b_2>0\) admitting an action of \((\mathbb{C},+)\) contains exactly \(b_2\) rational curves. It follows that the surface is a deformation of a blown-up primary Hopf surface.
