Dodgson condensation expressions we obtained for formula_48 and dividing out by formula_58 (this is allowed if one thinks of the identities as polynomial identities over the ring of polynomials in the formula_59 indeterminate variables formula_60). Dodgson condensation In mathematics, Dodgson condensation is a method of computing the determinants of square matrices. It is named for its inventor, Charles Lutwidge Dodgson (better known as Lewis Carroll). The method in the case of an "n" × "n" matrix is to construct an ("n" − 1) × ("n" − 1) matrix, an ("n" − 2) × ("n" − 2), and so on, finishing with a
Skeffington Lutwidge September. Lutwidge moved his flag to the new guard ship, the third rate in October, shifting again to in 1799. He became a vice-admiral of the red on 14 February that year, and by 1799 he was commander of the fleets in the Downs, where under his command in 1801 was his former midshipman of the "Carcass" Horatio Nelson, by now in command of . Lutwidge was advanced to admiral of the blue on 1 January 1801, admiral of the white on 9 November 1805, and admiral of the red on 31 July 1810. He retired from active service and
