In mathematics, the Birch and Swinnerton-Dyer conjecture is an open problem in the field of number theory. Its status as one of the most challenging mathematical questions has become widely recognized; the conjecture was chosen as one of the seven Millennium Prize Problems listed by the Clay Mathematics Institute, which has offered a $1,000,000 prize for the first correct proof. It is named after mathematicians Bryan Birch and Peter Swinnerton-Dyer who developed the conjecture during the first half of the 1960s with the help of machine computation. As of 2012, only special cases of the conjecture have been proved correct.
The conjecture relates arithmetic data associated to an elliptic curve E over a number field K to the behaviour of the Hasse–Weil L-function L(E, s) of E at s = 1. More specifically, it is conjectured that the rank of the abelian group E(K) of points of E is the order of the zero of L(E, s) at s = 1, and the first non-zero coefficient in the Taylor expansion of L(E, s) at s = 1 is given by more refined arithmetic data attached to E over K (Wiles 2006).

Famous quotes containing the words birch and/or conjecture:
“The birch stripped of its bark, or the charred stump where a tree has been burned down to be made into a canoe,—these are the only traces of man, a fabulous wild man to us. On either side, the primeval forest stretches away uninterrupted to Canada, or to the “South Sea”; to the white man a drear and howling wilderness, but to the Indian a home, adapted to his nature, and cheerful as the smile of the Great Spirit.”
—Henry David Thoreau (1817–1862)
“There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
