Mochizuki, Shinichi The intrinsic Hodge theory of \(p\)-adic hyperbolic curves. (English) Zbl 1052.14024 Doc. Math., Extra Vol. ICM Berlin 1998, Vol. II, 187-196 (1998). From the introduction: A hyperbolic curve is an algebraic curve obtained by removing \(r\) points from a smooth, proper curve of genus \(g\), where \(g\) and \(r\) are nonnegative integers such that \(2g-2+r>0\). If \(X\) is a hyperbolic curve over the field of complex numbers \(\mathbb{C}\) then \(X\) gives rise in a natural way to a Riemann surface \({\mathcal X}\). As one knows from complex analysis, the most fundamental fact concerning such a Riemann surface (due to P. Köbe [Acta Math. 50, 27–157 (1927; JFM 53.0032.01)]) is that it may be uniformized by the upper half-plane, i.e., \({\mathcal X}\approx {\mathfrak H}/ \Gamma\) where \({\mathfrak H}\overset \text{def}{=} \{z\in \mathbb{C}\mid \text{Im}(z)>0\}\), and \(\Gamma\approx \pi_1 ({\mathcal X})\) (the topological fundamental group of \({\mathcal X}\) is a discontinuous group acting on \({\mathfrak H}\). Note that the action of \(\Gamma\) on \({\mathfrak H}\) defines a canonical representation \[ \rho_{\mathcal X}:\pi_1({\mathcal X})\to \text{PSL}_2(R) \overset\text{def} {=} SL_2 (R)/\{\pm \}= \operatorname{Aut}_{ \text{Holomorphic}} ({\mathcal H}). \] The goal of the present manuscript is to survey various work of the author [Publ.
