On the class numbers of the fields of the p^n-torsion points of certain elliptic curves over Q
Fumio Sairaiji, Takuya Yamauchi
Let E be an elliptic curve over Q with prime conductor p. For each non-negative integer n we put K_n:=Q(E[p^n]). The aim of this paper is to estimate the order of the p-Sylow group…
