Arboreal Galois Groups of a PCF Map with Strictly Pre-periodic Critical Points

Özlem Ejder, Zofia Gołaska, Yasemin Kara +2

We study the arithmetic and geometric iterated monodromy groups associated to the postcritically finite (PCF) quadratic rational function $f(x)=\frac{2}{(x-1{)}^2}$ defined over a nu…
