Sažetak
Let E be an elliptic curve over Q given by y2 = f(x)
where f(x) = x(x − 1)(x − ). In this paper, we describe a construction
of twists E_g(u) of rank 2 over Q(u), where g(u) are polynomials over Q. The construction leads to two sets of twists: the first consists of five twists obtained by Rubin and Silverberg with a different method, while the second consists of five new twists.
