摘要:
本文证明了关于几何结构均匀化子的几个 Ax-Schanuel 型结果;我们的通用结果描述了均匀化子满足的偏微分方程的解之间的微分代数关系。特别地,我们给出了曲线上简单射影结构均匀化子(包括第一类 Fuchsian 群和任意亏格的均匀化子)的带有导数的完整 Ax-Schanuel 定理的证明。结合我们的技术与 Ax 的技术,我们得到了 j-函数和指数函数的导数组合的强 Ax-Schanuel 结果。在 Shimura 簇的一般设定中,我们得到了均匀化映射导数的 Ax-Schanuel 定理。我们的技术结合了微分几何、微分代数和微分闭域模型论的工具。
英文摘要:
In this paper, we prove several Ax-Schanuel type results for uniformizers of geometric structures; our general results describe the differential algebraic relations between the solutions of the partial differential equations satisfied by the uniformizers. In particular, we give a proof of the full Ax-Schanuel Theorem with derivatives for uniformizers of simple projective structure on curves including unifomizers of any Fuchsian group of the first kind and any genus. Combining our techniques with those of Ax, we give a strong Ax-Schanuel result for the combination of the derivatives of the j-function and the exponential function. In the general setting of Shimura varieties, we obtain an Ax-Schanuel theorem for the derivatives of uniformizing maps. Our techniques combine tools from differential geometry, differential algebra and the model theory of differentially closed fields.
