XXVI.—On the Eliminant of a Set of General Ternary Quadrics

Published online by Cambridge University Press:  06 July 2012

Extract

(1) The process of dialytic elimination was first applied to a set of general ternary quadrics by Sylvester in 1841, his method being to form from the three quadrics u1u2u3 ten cubics, viz.:—

and then eliminate dialytically the ten quantities

The actual work of obtaining the eliminant as a determinant of the 10th order he did not perform; and, indeed, with the notation which he used the labour would have been very irksome.
