introduction
- Belyi's theorem on algebraic curves
- any non-singular algebraic curve C, defined by algebraic number coefficients, represents a compact Riemann surface which is a ramified covering of the Riemann sphere, ramified at three points $\{0,1,\infty\}$ only.
- Belyi map gives rise to a projective curve
Belyi maps of degree 2
- Belyi map $f:\mathbb{P}^1\to \mathbb{P}^1$ defined by $z\mapsto z^2$
Grobner techniques
- start with three permutations $(12), (23), (132)$. They generate $S_3$.
- Riemann-Hurwitz formula gives the genus $g=1-3+(1+1+2)/2=0$
complex analytic method
- using modular forms
p-adic method
