BELYI FUNCTIONS OF THE SPECIAL WEIGHTED TREES OF \(\varvec{(2,3)}\)-TYPE
摘要
In this paper, we calculate the Belyi functions of the weighted trees of (2, 3)-type with primitive special edge rotation groups. There are 21 Galois orbits of these trees: 6 rational orbits, 12 orbits over quadratic fields, and 3 orbits over fields of degree 3, 4, and 6. The highest degree of the calculated Belyi function is 32. The calculations are performed using modular functions techniques.
