On the parity of ranks of Selmer groups II, by Jan Nekovar

Let E be an elliptic curve over Q with good ordinary reduction at a prime p. We show that the parity of the (co)-rank of the p-Selmer group of E is as predicted by the conjecture of Birch and Swinnerton-Dyer. (This is the same paper as before, with a few minor mistakes corrected.)
