....= 1, form a single orbit under the action of PSL 2 (Z=mZ) In x1 we prove Theorem 1. Let K a number eld and let m = 3; 4 or 5. Then the Tate Shafarevich group of an elliptic curve over K may contain arbitrarily many elements of order m. Special cases of this result are proved in [CaVI] B o] [Kr], McG] L] and [F1] Our method is that used in [F1] Since X(m) P 1 there are in nitely many elliptic curves E=K with E[m] m Z=mZ. We write : E E 0 and b : E E 00 for the isogenies with kernel m and Z=mZ respectively. We may estimate the Mordell Weil rank using either the ....

Quadratic Twists Of Modular Forms And Elliptic Curves - Ono, Papanikolas (2000)   (Correct)

....with an even number of prime factors. 2) All of the prime factors of each m i are in SE . Theorem 2.1 may also be used to prove the existence of non trivial elements of TateShafarevich groups of elliptic curves. Regarding Tate Shafarevich groups, works by Bolling, Cassels, Kramer, and Rohrlich [Bo, Ca, Kr, R] yield a variety of results concerning the nontriviality of the 2 and 3 parts of Tate Shafarevich groups for families of elliptic curves. Less is known about the non triviality of p parts of X(E) for primes p # 5. In this direction, Wong [Wo] proved that infinitely many quadratic twists of X 0 ....
