In mathematics, the Alexander polynomial is a knot invariant which assigns a polynomial with integer coefficients to each knot type. James Waddell Alexander II discovered this, the first knot polynomial, in 1923. In 1969, John Conway showed a version of this polynomial, now called the Alexander–Conway polynomial, could be computed using a skein relation, although its significance was not realized until the discovery of the Jones polynomial in 1984. Soon after Conway's reworking of the Alexander polynomial, it was realized that a similar skein relation was exhibited in Alexander's paper on his polynomial.

Famous quotes containing the word alexander:
“I thought when I was a young man that I would conquer the world with truth. I thought I would lead an army greater than Alexander ever dreamed of. Not to conquer nations, but to liberate mankind. With truth. With the golden sound of the Word. But only a few of them heard. Only a few of you understood. The rest of you put on black and sat in chapel.”
—Philip Dunne (1908–1992)
