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
Charles Dodgson (priest) College, Oxford, and who was a friend of Dodgson, used to walk over to visit Daresbury on Sundays, sometimes helping with the church services. Bayne would bring his son Vere, who became a lifelong friend of the young Charles Lutwidge.
