Abstract

First, inspired by a question of Sibony, we show that in every compact complex manifold YY with certain Oka property, there exists some entire curve f:CYf: \mathbb{C}\rightarrow Y generating all Nevanlinna/Ahlfors currents on YY, by holomorphic discs {fD(c,r)}cC,r>0\{f\restriction_{\mathbb{D}(c, r)}\}_{c\in \mathbb{C}, r>0}. Next, we answer positively a question of Yau, by constructing some entire curve g:CXg: \mathbb{C}\rightarrow X in the product X:=E1×E2X:=E_1\times E_2 of two elliptic curves E1E_1 and E2E_2, such that by using concentric holomorphic discs {gDr}r>0\{g\restriction_{\mathbb{D}_{ r}}\}_{r>0} we can obtain infinitely many distinct Nevanlinna/Ahlfors currents proportional to the extremal currents of integration along curves [{e1}×E2][\{e_1\}\times E_2], [E1×{e2}][E_1\times \{e_2\}] for all e1E1,e2E2e_1\in E_1, e_2\in E_2 simultaneously. This phenomenon is new, and it shows tremendous holomorphic flexibility of entire curves in large scale geometry.
