Popis: | We study model-complete fields that avoid a given quasi-project variety $V$. There is a close connection between hyperbolicity of $V$ and the existence of the model companion for the theory of characteristic-zero fields without rational points on $V$, extending the results for curves by Will Johnson and Jinhe Ye. In particular, we show that if $V$ is a Brody hyperbolic projective variety over $\mathbb{Q}$ with $V(\mathbb{Q}) = \varnothing$, then the model companion, called $V\mathrm{XF}$, exists. We also study some model-theoretic properties of $V\mathrm{XF}$. Comment: 23 pages |
