  • For fixed n 3 and nearly all values of , we show that there are only finitely many m such that g; m has a newly reducible n-th iterate. For nD 2 we show a similar result for a much more restricted set of . These results complement those obtained by Danielson and Fein (Proc. Amer. Math. Soc. 130:6 (2002), 1589‐1596) in the higher-degree case. Our method involves translating the problem to one of finding rational points on certain hyperelliptic curves, determining the genus of these curves, and… CONTINUE READING
