β¦ Synopsis
For (E) an elliptic curve over a number field (K), we give a lower bound, conditional on the "parity conjecture." for the number of quadratic twists of (E) whose Mordell-Weil rank is at least two. The main tool is a sieve-theoretic estimate of the number of square-free values of a homogeneous binary form. The results are a direct extension of those found by the author and B. Mazur (J. Amer. Muth. Soc. 4, 1991, 1-23). (: 1993 Academic Press, Inc.

The paper is devoted to exterior squares of polynomials and matrices over the finite field F q for large q. We find the limit as d β β of the probability that a monic polynomial f β F q [t] of degree d has root-free exterior square. We also find the limit as d β β of the probability that a matrix X
I-LLMP'I and Buhler et al. I'BLP], is a new routine for factoring integers. We present here a modification of that sieve. We use the fact that certain smoothness computations can be reused, and thereby reduce the asymptotic running time of the Number Field Sieve. We also give a way to precompute tab
