Zilber's Exponential Algebraic Closedness conjecture for semiabelian varieties

Let SS be a complex semiabelian variety of dimension nn, and write expS:CnS\exp_S: \mathbb{C}^n \to S for its exponential map. Let VCn×SV \subseteq \mathbb{C}^n \times S be a free and rotund subvariety. Zilber's Exponential Algebraic Closedness conjecture for semiabelian varieties. There is a point zˉCn\bar{z} \in \mathbb{C}^n such that (zˉ,expS(zˉ))V(\bar{z},\exp_S(\bar{z})) \in V. This extends the EAC formulation from algebraic tori to exponential maps of complex semiabelian varieties. The paper presents this as a conjecture and proves special cases when the variety has dominant projection to the domain; the general assertion remains open.
