“…Then, it does exist also a Kähler immersion into CP N of the Kähler submanifold of (C 2 , ω m ) defined by z 2 = 0, z 1 = z, endowed with the induced metric, having potential˜ m = u 2 + mu 4 , where u is defined implicitly by zz = e 2mu 2 u 2 . Observe that˜ m is the Calabi's diastasis function for this metric, since it is a rotation invariant potential centered at the origin (see [11] or also [35,Th. 3,p…”
