摘要：We answer a basic question in Nevanlinna theory ?that Ahlfors currents associated to the same entire curve may be ?nonunique. Indeed, we will construct one exotic entire curve which ?produces infinitely many cohomologically different Ahlfors currents. ?Moreover, concerning Siu's decomposition, for an arbitrary positive ?integer k or k=infinity, some of the obtained Ahlfors currents have ?singular parts supported on k irreducible curves. In addition, they ?can have nonzero diffuse parts as well, which answers a question of ?Brunella. This is joint work with Dinh Tuan Huynh (https://arxiv.org/abs/2101.11973).
