Abstract

We construct explicit families of quasi-hyperbolic and hyperbolic surfaces. This is based on earlier work of Vojta, and the recent expansion and generalization of it by the first author. In this paper we further extend it to the singular case, obtaining results for the surface of cuboids, the generalized surfaces of cuboids, and other families of Diophantine surfaces of general type. In particular, we produce explicit families of smooth complete intersection surfaces of multidegrees (m1,,mn)(m_1,\ldots,m_n) in Pn+2\mathbb{P}^{n+2} which are hyperbolic, for any n8n \geq 8 and any degrees mi2m_i \geq 2. We also show similar results for complete intersection surfaces in Pn+2\mathbb{P}^{n+2} for n=4,5,6,7n=4,5,6,7. These families give evidence for [Dem18, Conjecture 0.18] in the case of surfaces.
